摘要
用基团转移聚合法(GTP)合成嵌段共聚物是近年来国际上高分子研究的热门之一.在室温下制备嵌段共聚物是GTP的一大特点.本文利用三类不同GTP单体的活性差别,控制适当的加料顺序及聚合条件,首次用GTP法合成含丙烯腈嵌段的A-B型共聚物并进行表征.
Several kinds of A-B type block polymers with methacrylate, acrylate or acrylonitrile segments were prepared by means of group transfer polymerization and using dimethyl ketene methyl trimethylsilyl acetal as initiator and tetrabutyl ammonium bibenzoate as catalyst. The products were characterized by 1H NMR and FTIR.
