N‐Oxyl‐Controlled Radical Copolymerization of Styrene with Ethyl α‐Cyanocinnamate

Andreas Bartsch, Gudrun Schmidt‐Naake

Abstract

Abstract Summary: The block copolymers of styrene and ethyl α‐cyanocinnamate were prepared in dioxane and xylene with TEMPO‐capped polystyrene (PSTEMPO) as macroinitiator. The copolymerizations were carried out at 125 °C and 135 °C. The reactivity ratios were determined according to Kelen Tüdos and compared with the reactivity ratios from the radical copolymerization of styrene and ethyl α‐cyanocinnamate determined by Kohn et al. The influence of the comonomer ethyl α‐cyanocinnamate on the glass transition temperature was studied in comparison with the corresponding homopolystyrene.
