STUDY ON ACTIVATED TERMINATED POLYURETHANE RUBBER MODIFYING UNSATURATED POLYESTER RESIN Ⅱ:ACTIVATED TERMINATED POLYURETHANE RUBBER REDUCING SHRINKAGE OF UNSATURATED POLYESTER RESIN

通过在不饱和聚酯树脂中加入活性端基聚氨酯橡胶来降低树脂的体积收缩.树脂固化前,橡胶与不饱和聚酯树脂相溶性好;树脂固化时橡胶中的不饱和双键反应可参与反应,并呈一定粒径的胶粒析出.本文研究了几种活性端基聚氨酯橡胶对不饱和聚酯树脂收缩控制的影响.
