合成了１种新型聚合物单体—甲基丙烯酸（β－缩水甘油醚基）乙酯．将其用ＡＩＢＮ为引发剂进行自由基聚合，制得了聚甲基丙烯酸（β－缩水甘油醚基）乙酯，并进行聚合反应动力学研究，计算单体的聚合活化能。将聚合产物的各分级级分进行特性粘数、重均分子量和分子量分布指数的测定，订定这种聚合物于２５℃四氢呋喃中的Ｍａｒｋ－Ｈｏｕｗｉｎｋ方程为。

A novel monomer monomer methacrylate(2-glycidyl ether) ethyl ester was synthesised by reaction of β-chioroethyl glycidyl ether with potassium methacrylate and polymerised with AIBN as initiator at 65and 75℃.Moreover,this paper report the results of polymerization reaction kinetic and calculated the active energy E_a of polymerization.By fraction of polymethacrylate(2-glycidyl ether) ethyl ester and measurment of intrinsic viscosity,weight average molecular weight and molecular distribution for fraction samples,the established Mark-Houwink equation of this polymer in THF at 25℃ is given by
