GRAFT-COPOLYMERS OF POLY(METHYL METHACRYLATE) AND POLYTHIOPHENE

2-(2-Thienyl)ethyl methacrylate (2TEMA, 1), 2-(3-thienyl)ethyl methacrylate (3TEMA, 2) and 2-(N-pyrrolyl)ethyl methacrylate (PEMA, 3) were synthesized and copolymerized with methyl methacrylate (MMA) by radical initiation with AIBN. The reactivity ratios for the system MMA/2TEMA were determined to be r(MMA) = 0,57 +/- 0,09 and r(ETEMA) = 0,90 +/- 0,03. Thiophen was grafted onto the copolymers from 1-3 via oxidative polymerization in nitromethane. The graft copolymers were soluble as aggregates, and films cast from these solutions reached conductivities in the range of 0,2 to 0,4 S/cm.
