摘　　要：苯乙烯和丙烯酸β羟乙酯不同温度的竞聚率测定吴平平吴玉芳陆琛杨全兴韩哲文（华东理工大学材料科学研究所上海２００２３７）陈顺喜朱清仁（中科院中国科技大学结构分析开放实验室合肥２３００２６）关键词苯乙烯，丙烯酸β羟乙酯，共聚合，竞聚率丙烯酸β?..Bulk copolymerization of styrene (St, M 1)with β hydroxy ethyl acrylate (HEA, M 2)were carried out at 60,80.100,120 and 140℃ at two sensitive feed compositions.Compostions of copolymers were analyzed by elemental analysis (EA).The relative reactivity ratios were calculated by Error in Variable method (EVM) to be ( r 1=0 313, r 2=0 224),(0 349,0 225),(0 409,0 291),(0 525,0 327) and (0 565,0 347) at different temperatures.The differences of activation energies,entropies,and ethalpies between homopropagation and cross propagation,were calcutated too.
