Polycyanoaryl ether with thermoplastic resin

摘要

Disclosed is a novel polymer of this invention which comprises having a recurring unit represented by the formula: <IMAGE> (I) and having a reduced viscosity ( eta sp/c) of 0.2 dl/g or more at 60 DEG C. in a solution of a concentration of 0.2 g/dl in p-chlorophenol as a solvent, a method for preparing the same which comprises reacting a dihalogenobenzonitrile represented by the formula: <IMAGE> (II) wherein X represents a halogen atom, with an alkali metal salt of resorcin represented by the formula: <IMAGE> (III) wherein M represents an alkali metal, in the presence of a solvent; and then treating the reaction product obtained by water or alcohol, and molding materials and molded products employing the polycyanoaryl ether.
