✦ Synopsis

Poly[(methyl methacrylate)-co-(2-(N-pyrrolyl)ethyl methacrylate)] (PMMA-co-PEMA, 1) containing 0,7 to 7 mol-% pyrrolylethyl methacrylate (PEMA) units was crosslinked via oxidative polymerization with FeCl, in inert atmosphere. The properties of the products 2 depended on the amount of electroactive side groups and on the molecular weight of the precursor copolymers 1 as well as on the reaction conditions. Crosslinking between pendant pyrrolegroups and an increase in the glass transition temperature in the oxidative coupling could be avoided using precursor copolymers 1 with low PEMA content (< 1 mol-Yo).

## Abstract As part of a series of our works concerned with the elucidation of the crosslinking polymerization mechanism leading to the interpenetrating polymer network (IPN) formation, in which IPN consists of both polyurethane (PU) and polymethacrylate (PM) networks, this article deals with the p
