POLYMERIC MALONDIALDEHYDE DIANILS - A NOVEL TYPE OF ELECTRICALLY CONDUCTING POLYMERS

The reaction of vinamidinium salts with para-substituted aromatic diam ines gives rise to polymeric 2-aryl malonaldehyde dianils in good yeld s. polymeric cyanines can be obtianed from tetramethoxypropane and a p entamethine cyanine, respecitvely, and para-substituted aromatic diami nes. The degree of polymerisation P-n (n = 10 -40) was estimated by ne asuring the intrinisic viscoisty eta. The polymers show high electiral powder conducitivites (sigma = 0.03 - 50 S cm(-1)) after doping with iodine or FeCl3.
