【摘要】 <正> 基团转移聚合（GTP）是Webster等首先发现的一种新型的聚合方法。最常用的引发剂为甲基三甲基硅烷基二甲乙烯酮缩醛（MTS）。催化剂有负离子型（如HF₂^-,CN^-等）和Lewis酸型。Bandermann和Mai研究了甲基丙烯酸甲酯（MMA）的负离子催化剂的GTP动学。Hertler和Sogah报道了Lewis酸催化剂的聚合反更多还原

【Abstract】 GTP of MMA with zinc bromide catalyst in 1 , 2-dichloroethane solvent with dimethylketene methyl trimethyl silyl acetal (MTS) as initiator at 0℃ were studied. The relationship of MMA concentration with time at 0℃ were shown in Figure. The polymerization rate are zero order with respect to monomer concentration. The relationship of rate constant K between initiator concentrations [I] may be written as:The plots of In K against In [I] present the linear relationship, a is equal to 1.更多还原
