    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) (I) where R1 and R2 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 C3-C20-alkyl-substituted amino, or R1 is hydrogen and R2 is one of the above groups, or R1 and R2 form part of a cycloalkyl ring.
