Document Type and Number:
WIPO Patent Application WO/2021/215327
Kind Code:
A1
Abstract:
The present disclosure addresses the problem of providing a chlorine-containing polyether polyol which is highly reactive with an isocyanate and serves as a starting material for a polyurethane that exhibits excellent mechanical properties. A halogen-containing polyether polyol which is represented by formula (1) and has a molecular weight of from 500 to 10,000 and a degree of unsaturation of 0.02 meq/g or less, wherein the ratio of having structural unit (II) at an end is from 2 mol% to 99.5 mol%. (In formula (1), Q represents a polymer component that contains structural unit (I) and structural unit (II); m represents an integer from 2 to 3; and R1 represents an active hydrogen-containing compound residue.) (In formula (I), X represents a halogen atom.) (In structural unit (II), A represents a hydrogen atom or a hydrocarbon group having from 1 to 10 carbon atoms.)
