摘    要:以二甲基乙烯酮甲基三?基硅氧基缩?为引发剂,二氟化?四乙基铵为催化剂,进行了多种甲基丙烯酸酯和丙烯酸酯的基团转移聚合(GTP),发现甲基丙烯酸酯单体的酯基空间位阻对聚合起阻碍和减速作用,丙烯酸酯单体的酯基空间位则对聚合影响不大,聚甲基丙烯酸甲酯的分子量分布比聚丙烯酸甲酯的窄,溶剂的介电常数和溶剂与聚合物的溶度参数差值的影响聚合速率。

关 键 词:基因转移聚合  聚甲基?烯酸酯  聚丙烯酸酯

Abstract:Group transfer polymerization ( GTF ) of some methacrylates and acrylates was carried out by using 1-methoxy-1-(trimethylsiloxly)-2-methyl -1-propene (MTS )and Et4 NHF2 as initiator and catalyst, respectively. The rate of GTP decreased with increasing steric hindrance of methacrytates-monomer. Molecular weight distribution of PMA was broader than that of PMMA. The effccts of polarity and solubility parameter of solvent on rate of GTP were all so examined.
Keywords:Group transfer polymerization  Polymethacrylate  Polyacrylate
