摘要：

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