Method of producing polyether resins using phase transfer catalysts

A novel polyether resin having the repeating units of the formula: wherein Ar is a divalent aromatic group, and R1 and R2 are divalent aliphatic hydrocarbon groups having 1 to 4 carbon atoms, and method of producing same wherein alkylene dihalide and alkali metal salts of bifunctional phenols are re...

More Information
Summary:A novel polyether resin having the repeating units of the formula: wherein Ar is a divalent aromatic group, and R1 and R2 are divalent aliphatic hydrocarbon groups having 1 to 4 carbon atoms, and method of producing same wherein alkylene dihalide and alkali metal salts of bifunctional phenols are reacted in the presence of a phase transfer catalyst. The novel resin may be used, for example, as a film sheet or as an agent for improving the impact strength of polystyrene.
