✦ Synopsis

Abstract

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~2TEMA~ = 0,90 ± 0,03. Thiophen was grafted into 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.

## Abstract Polythiophene__‐graft‐__poly(methyl methacrylate) brushes are synthesized by ATRP. They form miscible blends with poly(vinylidene fluoride) (PVDF) due to specific interactions between the >CO groups of PT__‐g‐__PMMA with the >CF~2~ groups of PVDF. PT__‐g‐__PMMA remains in the interlame
