摘　　要：原子转移自由基聚合［１］，可同时适用于非极性单体和极性单体，如苯乙烯、二烯烃类和（甲基）丙烯酸酯、丙烯腈类单体［１～３］，这是传统的活性聚合如阴离子聚合和基团转移聚合所不及的；可以用于制备包括无规、嵌段、星形与高支化物在内的诸多结构清晰的高分子化合物...Copolymers of styrene(St) and butyl methacrylate(BMA) were prepared by atom transfer radical polymerization using a bifunctional initiator bis(chloroethyl)benzene. The molecular weights of the polymers were determined by gel permeation chromatography. The block copolymers of BMA and St with predicted molecular weight (11047104) and narrow molecular weight distribution (1218) were obtained. The random copolymer compositions were determined by 1H NMR spectroscopy and the reactivity ratios were evaluated by the extended KelenTudos method to be rSt=081, rBMA=016. St was found to be more reactive than BMA in atom transfer radical copolymerization.
