ABSTRACT:
A hydroxy-substituted poly(phenylene ether) resin can be produced by copolymerizing from 1.5 to 8 mol % of a phenol compound selected from those represented by the following formulae (a), (b), (c), (d), and (e): ##STR1## and from 98.5 to 92 mol % of a phenol compound of the following formula (f): ##STR2## The hydroxy-substituted poly(phenylene ether) resin shows excellent compatibility with a polyamide, a polycarbonate, a poly(butylene terephthalate), a poly(phenylene sulfide), and is useful as a copatibilizer or a modified resin for engineering plastics.
