POLYALKYLENE CARBONATE DIOL HAVING CYCLIC ALKYLENE GROUP, COPOLYMER THERE OF, AND METHOD FOR PRODUCING THEM

摘要

PROBLEM TO BE SOLVED: To provide a novel polyalkylene carbonate diol using a cyclic alkylene diol in which a hydroxyl group is bonded to a secondary or tertiary carbon atom, a copolymer thereof, and methods for producing the polyalkylene carbonate diol having a cyclic alkylene group and the copolymer thereof, the method easily controlling the composition of the copolymer.;SOLUTION: The polyalkylene carbonate diol copolymer has molecular structure of a repeating unit represented by formula (A) containing a cyclic alkylene group Z and a repeating unit represented by formula (B), and has a molecular terminal of a hydroxyl group.;COPYRIGHT: (C)2013,JPO&INPIT
