GRAFT-COPOLYMERS AND COMPOSITES OF POLY(METHYL METHACRYLATE) AND POLYPYRROLE .1.

Pyrrole (Py) 2 was grafted onto a poly(methyl methacrylate) (PMMA) bac kbone which already contained the Py moiety within, via oxidative poly merization with FeCl3 in nitromethane. Graft copolymers 3 with very lo w Py amounts were soluble but they became rapidly insoluble with incre asing Py content due to the formation of long Py sequences. The proper ties of the graft copolymers 3, as well as of films cast from the reac tion mixture, depended on several reaction conditions. The products 3 were characterized using elemental analysis, UV-Vis, gel permeation ch romatography and differential scanning calorimetry.
