ABSTRACT:
High molecular weight polyphenylene ethers are prepared from monohydric phenols by a conventional polycondensation, by a method in which the resulting polymers are reacted with an epoxide of the general formula (I) ##STR1## where R.sup.1 and R.sup.2 can be identical or different and are each alkyl, cycloalkyl, aryl, aryloxy, alkoxy or carboxyalkyl, each of which may contain a further epoxide group, or C.sub.3 -C.sub.20 -alkyl-substituted amino, or R.sup.1 is hydrogen and R.sup.2 is one of the above groups, or R.sup.1 and R.sup.2 form part of a cycloalkyl ring.
