  • Patent number: 9963563
    Abstract: The embodiments of the present disclosure present systems and methods for the reversible solubilization of (aryl ether ketones) (PAEKs). A thioacetalization process is employed to modify the PAEKs into poly (aryl ether thioacetals) which, unlike PAEKs, are substantially soluble in common solvents. This modification allowing selected analysis techniques to be more easily performed on PAEKs, such as gel permeation chromatography. The thioacetalization may be reversed through a deprotection reaction to recover the original PAEK without substantial degradation, allowing for non-destructive characterization of the PAEK. Advantageously, the thioacetalization process is generally applicable to a broad range of PAEKs, unlike presently known methods of solubilizing PAEKs. Solubilization of PAEKs further expands the utility of the PAEKs, opening up additional routes to chemical modification of PAEKs, as well as allowing for the possibility of processing PAEKs from solution.

The PBI is mixed with sulfuric acid at a temperature between 40° C. and 80° C. for 30 minutes to 2 hours to produce a PBI solution then cooled to room temperature to form a cooled PBI solution. Then PEKK is added to the cooled PBI solution to form a mixture and that mixture is stirred from 30 minutes to 2 hours at room temperature to form a stirred mixture. The stirred mixture is poured into an excess of water being stirred swiftly to form an aqueous mixture. The aqueous mixture is filtered to produce a blend. The blend is washed with water and dried.

  • Patent number: 8795841
    Abstract: Disclosed is a graft polymerization method which has solved problems involved in use of a solvent, a radical initiator and high-energy radiation when a monomer is graft-polymerized on the surface of a polymer base. The graft polymerization method is characterized in that a polymerization product is obtained by immersing a polymer base (i) having a ketone group on the surface into a reaction system containing a monomer (ii) and then irradiating the polymer base (i) with light so that polymerization of the monomer starts from the surface of the polymer base (i).

  • Publication number: 20140093728
    Abstract: A carbon nanostructure that is free of a growth substrate can include a plurality of carbon nanotubes that are branched, crosslinked, and share common walls with one another. The carbon nanostructure can be released from a growth substrate in the form of a flake material. Optionally, the carbon nanotubes of the carbon nanostructure can be coated, such as with a polymer, or a filler material can be present within the porosity of the carbon nanostructure. Methods for forming a carbon nanostructure that is free of a growth substrate can include providing a carbon nanostructure adhered to a growth substrate, and removing the carbon nanostructure from the growth substrate to form a carbon nanostructure that is free of the growth substrate. Various techniques can be used to affect removal of the carbon nanostructure from the growth substrate. Isolation of the carbon nanostructure can further employ various wet and/or dry separation techniques.

  • Publication number: 20130323416
    Abstract: The invention relates to heat treatment of polymorphic semicrystalline or crystallizable polymers to increase the content of the highest melting crystalline form. Such heat treatment results in a polymer powder that has a consistent, uniform melting range, improved flow and improved durability of the powder particle size for applications that require powder flow at elevated temperatures. In addition to improved powder properties, the articles produced from the powders also exhibit better physical properties in both appearance and in mechanical properties. Thus the invention also includes polymer powders and articles produced by the described processes.
