Patent number: 6809817Abstract: The present invention relates to methods and devices for in-situ measurement of reaction components of interest during manufacturing of polycarbonate by melt polymerization. The present invention describes irradiating a molten polymer sample with UV/visible light, and generating an absorbance profile correlated to Fries products as well as uncapped phenolic groups in the sample. The methods and apparatus of the invention are suitable for monitoring of Fries products in reactions ranging in size from small scale combinatorial formats to production scale reactors. Also included in methods of the invention are univariate and multivariate analysis for prediction of linear Fries, branched Fries and uncapped phenolic end-groups in unknowns.Type: GrantFiled: August 24, 2001Date of Patent: October 26, 2004Assignee: General Electric CompanyInventors: Radislav Alexandrovich Potyrailo, Patrick Joseph McCloskey, James Day

Patent number: 6790929Abstract: This invention relates to an extrusion method preparing polycarbonates from a solution of an oligomeric polycarbonate. A mixture of bis(methyl salicyl)carbonate (BMSC), BPA and a transesterification catalyst are first equilibrated at moderate temperatures to provide a solution of polycarbonate oligomer in methyl salicylate. The solution is then fed to a devolatilizing extruder, where the polymerization reaction is completed and the methyl salicylate solvent is removed. The solution comprising the oligomeric polycarbonate can also be pre-heated under pressure to a temperature above the boiling point of methyl salicylate and subsequently fed to a devolatilizing extruder equipped for rapid flashing off the solvent. The method provides polycarbonate with greater efficiency than the corresponding process in which unreacted monomers are fed to the extruder. Additionally, the method of the invention does not require the isolation of a precursor polycarbonate comprising ester-substituted phenoxy terminal groups.Type: GrantFiled: March 17, 2003Date of Patent: September 14, 2004Assignee: General Electric CompanyInventors: Norberto Silvi, Mark Howard Giammattei, Patrick Joseph McCloskey, Alberto Nisoli, James Day, Narayan Ramesh, Paul Michael Smigelski, Jr., Paul Russell Wilson

Publication number: 20040138383Abstract: A method of preparing block copolymers by solid state polymerization is described. A mixture of a partially crystalline polycarbonate having activated terminal aryloxy groups, for example terminal methyl salicyl groups, when heated together with an oligomeric polyester having reactive terminal hydroxy groups under solid state polymerization conditions affords block copolymers. The activated terminal aryloxy groups play a key role in preserving the block lengths of the starting materials. A control sample in which the partially crystalline polycarbonate lacks activated terminal aryloxy groups, for example polycarbonates substituted by phenol, affords a much lower molecular weight, more highly randomized copolymer product. The product block copolymers are useful as “weatherable” plastic materials.Type: ApplicationFiled: December 22, 2003Publication date: July 15, 2004Inventors: Gregory Allen O'Neil, James Day, Daniel Joseph Brunelle, Joseph Anthony Suriano, Patrick Joseph McCloskey, Paul Michael Smigelski

Publication number: 20040068086Abstract: Usually, polycarbonate polymerization is limited by the rate at which inhibitory byproducts, such as phenol and salicylate, can be removed from the reaction. To facilitate the removal of volatile reaction byproducts from the reaction as polymerization occurs, the present invention provides a spray mist reactor. The formation of a spray mist polymerization reaction allows for the creation of an enormous surface area for exchange of volatile byproducts. The present invention is applicable to polymerization of polycarbonate and its copolymers starting with monomers or oligomers. The invention may be used to increase throughput and minimize initial investment for a give melt process, especially the fast reacting bis(methylsalicylate) carbonate process.Type: ApplicationFiled: October 4, 2002Publication date: April 8, 2004Inventors: James Day, Patrick J. McCloskey, Paul M. Smigelski

Patent number: 6518391Abstract: Solid state polymerization of partially crystalline polycarbonate oligomers bearing ester-substituted terminal groups occurs at useful reaction rates despite their high level of endcapping. Partially crystalline polycarbonate oligomers having ester substituted terminal groups may be obtained in a single step by reaction of an ester substituted diaryl carbonate such as bis-methyl salicyl carbonate with a dihydroxy aromatic compound such as bisphenol A in the presence of a transesterification catalyst such as sodium hydroxide. Alternatively, amorphous oligomeric polycarbonates incorporating ester substituted endgroups may be obtained through careful control of the melt reaction conditions. The amorphous oligomeric polycarbonates are crystallized upon exposure to solvent vapor and subsequently undergo solid state polymerization at synthetically useful reaction rates.Type: GrantFiled: July 24, 2001Date of Patent: February 11, 2003Assignee: General Electric CompanyInventors: Patrick Joseph McCloskey, James Day, Paul Michael Smigelski, Jr., Timothy Brydon Burnell

Patent number: 6506871Abstract: Extrusion of a mixture of an ester-substituted diaryl carbonate, such as bis(methyl salicyl) carbonate, a dihydroxy aromatic compound such as bisphenol A and a transesterification catalyst such as tetrabutylphosphonium acetate (TBPA) affords polycarbonate having a weight average molecular weight of greater than 20,000 daltons. The extruder is equipped with one or more vacuum vents to remove by-product ester-substituted phenol. Similarly, a precursor polycarbonate having ester-substituted phenoxy endgroups, for example methyl salicyl endgroups, when subjected to extrusion affords a polycarbonate having a significantly increased molecular weight relative to the precursor polycarbonate. The reaction to form a higher molecular weight polycarbonate may be catalyzed by residual transesterification catalyst present in the precursor polycarbonate, or by a combination of any residual catalyst and an additional catalyst such as TBPA introduced in the extrusion step.Type: GrantFiled: June 12, 2002Date of Patent: January 14, 2003Assignee: General Electric CompanyInventors: Norberto Silvi, Patrick Joseph McCloskey, James Day, Mark Howard Giammattei

Publication number: 20020182279Abstract: The present invention discloses an apparatus and method for pelletizing polycarbonate oligomers and polymers. A heated pressurizable cylinder holds aggregate polycarbonate oligomers or polymers which becomes a melt. The bottom of the cylinder is connected to a distributor plenum having nozzles. A funneling device receives the polymer droplets that emerge from the plenum and channels them into a container that has a screen on the top that collects the product pellets. Finally, a blowing agent, such as phenol, can be added to the melt to impart small voids in the product pellets.Type: ApplicationFiled: May 31, 2001Publication date: December 5, 2002Inventor: James Day

Patent number: 6466428Abstract: A multilayer cell is provided that comprises two solid, nonporous current collectors, two porous electrodes separating the current collectors, a porous separator between the electrodes and an electrolyte occupying pores in the electrodes and separator. The mutilayer cell is electrolyzed to disassociate water within the cell to oxygen gas and hydrogen gas. A vacuum is applied to the cell substantially at the same time as the electrolyzing step, to remove the oxygen gas and hydrogen gas. The cell is then sealed to form a ultracapacitor substantially free from water.Type: GrantFiled: September 5, 2000Date of Patent: October 15, 2002Assignee: General Electric CompanyInventors: Chang Wei, Elihu Calvin Jerabek, James Day

Patent number: 6365703Abstract: The present invention discloses a vapor phase method of introducing a branching agent such as THPE into a solid polycarbonate while simultaneously crystallizing the solid polycarbonate. The partially crystalline polycarbonate containing a branching agent introduced in this manner is suitable for use in the preparation of branched polycarbonates by solid state polymerization. Branching in the polycarbonates so produced is demonstrated by rheometric measurements. Such branched polycarbonates are known to possess increased material melt strength, shear sensitivity, and complex viscosity ratio, and are particularly well-suited in blow molding applications.Type: GrantFiled: May 31, 2001Date of Patent: April 2, 2002Assignee: General Electric CompanyInventors: James Day, Sukhendu Bikash Hait
