摘　　要：首次合成了甲基丙烯酸乙酰（丙酰、正丁酰及异丁酰）氧乙酯新型单体，对其结构进行了鉴定。通过粘度法和小角激光散射法，确立了诸单体均聚物的Ｍａｒｋ－Ｈｏｕｗｉｎｋ方程，并详细讨论了均聚物产生支化的机理。Acetoxyethyl-, propionyloxyethyl-, buthyloxyethyl-,and isobuthyloxyethyl methacrylate were synthesized and characterized for the first time successfully. Homopolymers with high molecular weight were obtained by radical polymerization. by radical polymerization. By measuring with light scattering and viscosity, the Mark-Houwink equations of them were obtained, The relationship between lg[η]and lg was studied and their branching reaction were also discussed.
