基团转移聚合(Group Transfer Polymerization,GTP)作为一种新的加聚方式,由于具有室温下使极性单体快速聚合;得到预期分子量和窄分子量分布的聚合物;可进行活性聚合,制备嵌段共聚物,对合成丙烯酸酯类橡胶或热塑性弹性体极为有利;可合成带有功能性端基和遥爪的聚合物等优点,近几年来发展迅速。到目前为止,最有效和最常用的GTP引发剂是二甲基乙烯酮甲基三甲基硅基缩醛 Group Transfer Polymerization (GTP) is a new polyaddition method, which has the advantages of rapid polymerization of polar monomers at room temperature, obtaining polymers with the expected molecular weight and narrow molecular weight distribution, living polymerization, Segment copolymers are extremely advantageous for the synthesis of acrylic or thermoplastic elastomers; the advantages of synthesizing polymers with functional end groups and telechews have been rapidly developed in recent years. To date, the most effective and commonly used GTP initiators are dimethyl ketene methyl trimethylsilyl acetal
