Method for the production of a polyether resin.

摘要

The invention relatos to a novel polyether resin containing alternating aromatic and aliphatic groups. The novel polyether resin can be represented by the general formula …… wherein R<1> and R<2> are divalent aliphatic hydrocarbon groups having from one to four carbon atoms and Ar is a divalent aromatic group. The invention further relates to a method for the production of the novel polyether resin which comprises reacting an alkali metal salt of a bifunctional phenol with an alkylene dihalide in the presence of a phase transfer catalyst.
