The present invention relates to novel polyether polyols containing pendant amine group and to a process for their preparation. These polyether polyols have molecular weights of from about 105 to about 35,000, and contain at least one terminal hydroxyl group and at least one pendant amine group. The process for their preparation comprises reacting a compound containing from 1 to 10 hydroxyl groups and a molecular weight of about 32 to about 15,000 with at least one epoxide which contains one or more halogen atoms, in the presence of one or more DMC catalysts, to form an intermediate polyether polyol which contains halogenated carbon atoms; then reacting this intermediate polyether polyol with an amine group containing compound having from 1 to 3 primary, secondary and/or tertiary amine groups.
本发明涉及含有悬垂胺基团的新型聚醚多元醇及其制备工艺。这些聚醚多元醇的分子量从约 105 到约 35,000 不等,并含有至少一个末端羟基和至少一个悬垂胺基团。其制备工艺包括:在一种或多种
DMC 催化剂存在下,将含有 1 至 10 个羟基、分子量约为 32 至 15,000 的化合物与至少一种含有一个或多个卤素原子的
环氧化物反应,生成一种含有卤化碳原子的中间体聚醚多元醇;然后将这种中间体聚醚多元醇与含有 1 至 3 个
伯胺、仲胺和/或叔胺基团的含胺基团化合物反应。
