摘要
分别采用溴化苄、2溴丙二酸二乙酯和2溴2甲基丙二酸二乙酯作引发剂,在CuBr/2,2′联吡啶配位化合物催化下,进行了苯乙烯的原子转移自由基聚合,在90~130℃范围内研究了温度对聚合反应速率及所得聚合物相对分子质量及其分布的影响。实验发现。
The effect of temperature on the atom transfer radical polymerization (ATRP) of styrene in the range of 90130 catalyzed by CuBr/2,2bipyridine complex with benzyl bromide, ethly 2bromomalonate and diethyl 2bromo2methylmalnate as initiators respectively was invegasted. It was found that the polymerization rate reached the maximum at about 110 for all these three initiators.
