Abstract:

A self-doped copolymer of pyrrole and potassium 3-1-pyrrolyl propane sulfonate has been prepared and studied electrochemically and with FT-IR. Ionic mobiolities through the film have been measured. Copolymers of pyrrole and N--3-bromophenyl pyrrole were shown to have conductivities which decreased by 100,000 with 12 of the bromo compound. Proton mobility and conductivity in polypyrrole tosylate films have been studied as a function of pH. PRDDO calculations of polypyrrole oligomers and of oligomers with an N-phenyl ring on a central pyrrole have been carried out, including geometry optimization in the latter systems to see the effect of the substituent on the twisting of the planar system. Several polyorganophospha- lambda 5 -azenes have been prepared and studied and have been shown to be quite thermally stable. Base catalyzed polymerization of alpha -dibromoxylenes has been shown to give ether linkages, in addition to polyp-phenylenevinylene, depending on the isomeric starting material. Copolymerization of 1,3-cyclohexadiene and 2-chloroacrylonitrile gives a polymer containing both 1,2, and 1,4 linkages through the cyclohexene rings.
