20110040045 | REVERSIBLE DERIVATIZATION OF POLY (ARYL ETHER KETONES) - 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 PAEKs1 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. | 02-17-2011 |

20130035454 | POLYBENZIMIDAZOLE-POLYETHERKETONEKETONE BLENDS AND MISCIBLE BLENDS - A process for producing a solution blend of a polybenzimidazole (PBI) and a polyetherketoneketone (PEKK). 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. The resulting blend can yield a blend in all proportion from 1/99 PBI/PEKK to 99/1 PBI/PEKK. | 02-07-2013 |
