  • Publication number: 20110229674
    Abstract: The polymerization processes described herein provide methods for controlling the dehydration of glycols such that dimers are formed as glycol ethers and incorporated into aliphatic-aromatic copolyetheresters during polycondensation. Control over this phenomenon provides unique polymer compositions with a range of thermo-mechanical properties, crystallinity, bio-content and biodegradability.

  • Publication number: 20110031441
    Abstract: There are provided electrically conducting polymer compositions comprising an electrectically conductive polymer or copolymer and an organic solvent wettable fluorinated acid polymer. Electrically conductive polymer materials are derived from thiophene, pyrrole, aniline and polycyclic heteroaromatic precursor monomers. Non-conductive polymers derived from alkenyl, alkynyl, arylene, and heteroarylene precursor monomers. The organic-solvent wettable fluorinated acid polymer is fluorinated or highly fluorinated and may be colloid-forming. Acidic groups include carboxylic acid groups, sulfonic acid groups, sulfonimide groups, phosphoric acid groups, phosphonic acid groups, and combinations thereof. The compositions can be used in organic electronic devices.
