ABSTRACT:
Disclosed is a process for preparing a polyhydroxyphenylene ether resin which comprises copolymerizing a phenol-substituted compound having hydroxyl group as a substituent, represented by the formula (I): ##STR1## wherein m and n each represents an integer satisfying the formulae 1.ltoreq.m and m+n.ltoreq.4; J represents {(HO).sub.a --R.sup.1 --S}.sub.b --R.sup.2 -- where a and b each represents an integer of 1 to 6; and R.sup.1 and R.sup.2 each represents unsubstituted or halogen-substituted alkylene, alkenylene or arylene, or alkylene; K represents halogen, primary or secondary alkyl, alkenyl, phenyl, aminoalkyl, haloalkyl, hydrocarbonoxy or halohydrocarbonoxy;
with at least one phenol-substituted compound represented by the formula (II): ##STR2## wherein Qs each represents hydrogen, halogen, primary or secondary alkyl, alkenyl, aromatic, aminoalkyl, haloalkyl, hydrocarbonoxy or halohydrocarbonoxy,
and a resin composition containing the polyhydroxyphenylene ether resin prepared by the above method.
