发明名称 POLYETHER POLYMER AND PRODUCTION PROCESS THEREOF
摘要 A polyether polymer containing a defined polymerization unit (—R1—O—R2—O—), R1 and R2 being derived from monomers (A) and (B), respectively; and a process for producing the polyether polymer comprising the step of copolymerizing the monomer (A) with the monomer (B) in the presence of a metal salt, wherein the monomer (A) is (A1) a non-conjugated mono-cyclic diene compound containing a cyclic skeleton, or (A2) a non-conjugated cyclic diene compound containing a mutual linking of plurality of a mono-cyclic structure having a cyclic skeleton, and the monomer (B) is an aliphatic diol, an alicyclic diol or a divalent phenol.
