The polymerization method can afford regioregular poly(3-alkylthiophenes) in high yields. Kinetic study of polymerization revealed the living character of this process.

Sequential monomer addition resulted in new block copolymers containing different poly(3-alkylthiophene) segments, which further confirms the “livingness” of this system. Other synthetic methods can be used as well to conduct living polymerization. Blends and electronic devices can be prepared.Type: GrantFiled: October 13, 2008Date of Patent: November 16, 2010Assignee: Carnegie Mellon UniversityInventors: Richard D. McCullough, Elena E.

Patent number: 7432339Abstract: A method for producing polyphenylene sulfide (PPS) polymer, including polymerizing reactants in a reaction mixture in a vessel to form PPS polymer in the vessel, measuring values of operating variables of the vessel and/or PPS process, and determining the amount of quench fluid to add to the vessel based on the values of the operating variables.

The organic monothiol compound can be added at any time prior to substantial completion of polymerization to provide arylene sulfide polymers of increased extrusion rate.Type: GrantFiled: February 11, 1988Date of Patent: March 22, 1994Assignee: Phillips Petroleum CompanyInventors: Jon F. Geibel, Robert W. Campbell, Guy Senatore, Fernando C. Vidaurri, Mark A. Haney

Patent number: 5162470Abstract: Novel conjugated stilbenylene polymers are disclosed having non-linear optical properties, and which can be converted to electrically conductive polymers. Such polymers are produced by reacting a novel bis-cycloalkylene sulfonium salt of 2,5-dimethyl stilbene, e.g. 2,5-(4' -methoxy)-stilbene dimethylene bis-(tetramethylene sulfonium bromide), with alkali metal hydroxide to form a cycloalkylene sulfonium salt precursor polymer, and then heating the precursor polymer under conditions to produce the stilbenylene vinylene polymer, e.g. poly(2,5-(4'-methoxy)stilbenylene vinylene).Type: GrantFiled: April 9, 1991Date of Patent: November 10, 1992Inventor: John Stenger-Smith

Patent number: 5097008Abstract: Branched polycarbonates are prepared by melt equilibration of aromatic cyclic polycarbonate oligomers with a polyhydric phenol having more than two hydroxy groups per molecule, preferably 1,1,1-tris-(4-hydroxyphenyl)ethane, in the presence of a carbonate equilibration catalyst, preferably tetrabutylammonium tetraphenylborate. In an additional embodimetn of the invention, a linear aromatic polycarbonate is added to the reaction mixture. Branched polycarbonates prepared according to this inventin have high melt strength and high shear sensitivity characteristics and are useful in extrusion and injection molding processing applications and particularly useful in blow molding applications for preparing relatively large articles and panels.Type: GrantFiled: May 10, 1990Date of Patent: March 17, 1992Assignee: General Electric CompanyInventors: Herman O. Krabbenhoft, Eugene P. Boden

Patent number: 4972039Abstract: Polycyclic polycarbonate (or thiol analog) oligomers are prepared from a mixture of at least one bishaloformate with at least one tetraphenol, or thio analogs thereof. Such mixture may also contain at least one dihydroxy or dimercapto compound. The oligomers are formed by the reaction of such mixtures with alkali metal hydroxides and various amines. The polycyclic oligomer mixtures may be converted to crosslinked polycarbonates or their thiol analogs.Type: GrantFiled: September 11, 1989Date of Patent: November 20, 1990Assignee: General Electric CompanyInventors: Thomas G. Shannon, Daniel J. Brunelle

Patent number: RE40813Abstract: The present invention relates to polythiophenes, particularly regioregular head-to-tail poly(3-alkylthiophenes) (HT-PATs), block copolymers made therefrom, and their methods of formation. The present invention provides HT-PATs with well-defined, specific end-groups, functionalization of the defined HT-PATs, and incorporation of end group functionalized HT-PATs into block copolymers with structural polymers. The intrinsically conductive diblock and triblock copolymers, formed from the HT-PATs, have excellent conductivity and low polydispersities that are useful in a number of applications. The block copolymers of the present invention have been found to exhibit conductivities that range from a low of 10?8 S/cm for certain applications to as high as several hundred S/cm or more.Type: GrantFiled: August 4, 2005Date of Patent: June 30, 2009Assignee: Carnegie Mellon UniversityInventors: Richard D.
