POLYETHER POLYMER AND PROCESS FOR PRODUCING THE SAME |
摘要 |
A process for producing a polyether polymer by polymerizing a monomer having an oxirane group in the presence of a Lewis base having no active hydrogen such as, for example, a nitrile compound, a cyclic ether compound or an ester compound; and a polyether polymer produced by this process. Thus, a polyether polymer having a minimized amount of undesirable crosslinked product can be produced without reduction of polymerization activity.
