EnglishAcrylic and methacrylic monomers bearing pyrrolyl, thienyl and terthienyl groups, were synthesized and copolymerized with various amounts of butyl acrylate and butyl methacrylate. In the resulting copolymers the heterocycle side-groups behaved as initiators in the oxidative polymerization of thiophene, allowing the polythiophene chains to grow from the side-groups and leading therefore to graft copolymers. These last were collected mostly as insoluble fractions after extraction with chloroform. Processible polymers with polythiophene side-chains were obtained when in the precursor polymer the heterocycle side-group content was very low. The presence in the graft copolymers of a significant number of stiff polythiophene side-chains was responsible for the rise in Tg values in comparison with the precursor polymers. The average number of grafted thiophene units, evaluated in the range 2-7.5, did not relate directly to measured conductivity values that were in the range 5.9 x 10(-5)-6.2 x 10(-2) Scm(-1).
