Abstract

A copolymer comprising PA1 a) a segment A with a number-average molar mass Mn of from 1000 to 20,000 g/mol, which has PA2 i) units 1, which have been derived from structures of the formula (I) ##STR1## where the radicals R.sup.1 and R.sup.2, independently of one another, are a hydrogen, fluorine, chlorine or bromine atom or a branched or unbranched alkyl or alkoxy radical having from 1 to 6 carbon atoms; and/or PA2 ii) units 2, which are derived from structures of the formula (II) ##STR2## and b) a segment B, derived from a polyarylene sulfide structure of the formula (IV) ##STR3## where Ar is an aromatic radical, or more than one condensed aromatic radicals, and n is a number from 2 to 100, in particular from 5 to 20, together with a process for its preparation, and also its use for compatibilizing blends made from polyarylene sulfides and aromatic polyesters.
