基团转移聚合新引发剂——1-(N,N-二甲氨基)-1-三甲基硅氧基丁烯-1的合成与性质的研究

THE SYNTHESIS AND PROPERTIES OF A NEW INITIATOR FOR GTP——1-(N,N-DIMETHYLAMINO-)-TRIME- THYLSILOXY BUTENE-1

本文报道了一种新的基团转移聚合引发剂——1-(N,N-二甲氨基)-1-三甲基硅氧基丁烯-1,对由其引发的GTP、其引发活性、与催化剂及单体用量比对聚合速度、分子量分布的影响进行了研究,得到了分散性较小的实测分子量和理论分子量相近的PMMA。

A new initiator for group transfer polyme ization-1-(N, N-dimethylamino-)-1-trime-thylsiloxy butene-1 has been synthesized, The initiation activity of the new initiator, the effect of the catalyst/initiator ratio and monomer/initiator ratio on the rate of reaction and molecular weight distribution have been investigated. PMMA with narrow molecular weight distribution and predetermined molecular weight were obtained.
