Disclosed is a process for delaying the metathesis polymerization of strained ring non-conjugated, cycloolefins in which the cycloolefin, a metathesis polymerization catalyst, an activator selected from the group consisting of alkylaluminum, alkylzinc and alkyltin compounds, and a reaction rate moderator are charged into a mold, the reaction rate moderator being a phosphorus-containing compound that includes various aryl phosphates, aliphatic phosphates, aliphatic phosphites, aryl phosphites, aryl phosphines and alkyl phosphines.
本发明公开了一种用于延迟应变环非共轭环烯烃的偏聚聚合反应的工艺,在该工艺中,环烯烃、偏聚聚合催化剂、从烷基铝、烷基锌和烷基锡化合物组成的组中选出的活化剂以及反应速率调节剂被注入模具中,反应速率调节剂是一种含磷化合物,包括各种芳基膦酸盐、脂肪族膦酸盐、脂肪族亚磷酸盐、芳基亚磷酸盐、芳基膦和烷基膦。
