Production manner of the polyalkylene oxide which possesses ether linkage and ester join in the end.

摘要

PROBLEM TO BE SOLVED: To obtain a polyalkylene oxide bearing an ether linkage and an ester linkage at its end by polymerizing an alkylene oxide compound in the presence of a nonmetallic catalyst and an ester compound.;SOLUTION: An alkylene oxide compound is polymerized at 200°C or below in the presence of 1×10-15-5×10-1 mole, based on 1 mole of the alkylene oxide compound, of a nonmetallic catalyst such as a phosphazenium compound, a phosphine oxide compound, a phosphine sulfide compound, represented by formula I, II and III, respectively, and the like, and 1-1×105 mole, based on 1 mole of the non-metallic catalyst, of an ester compound to give a polyalkylene oxide bearing an ether linkage at an initiation terminal and an ester linkage at a propagating terminal. The ester compound is composed of a 1-20C aliphatic or alicyclic alcohol or the like and an aliphatic or alicyclic carboxylic acid or the like. In the formulae, R is a 1-10C hydrocarbon; Z is a halogen anion, a hydroxy anion, an alkoxy anion or the like; and x is 0-5.0.;COPYRIGHT: (C)2001,JPO
