摘要
本文利用环氧基功能团与羟基反应，使聚酯分子扩链，合成了A—B—A型嵌段共取物，其耐酸碱性比普通型不饱和聚酯强可与3301双酚A型不饱和聚酯媲美，提高了聚酯的耐碱性。
he A-B-A model block copolymers were synthesized by chain-enlarged reaction of unsaturated polyester (UP) and diepoxy prepolymers. Their alkali and acid resistivity was better than common UP and compared favourably with that of 33O1 UP.
