摘要:
The present invention relates to epoxide resins containing phenol groups and to homo-oligomers thereof of the structure ##STR1## that are obtained by reacting phenolcarboxylic acids with one epoxide equivalent of a polyepoxide. The new compounds are difficultly volatile and resistant to migration and can be used as stabilizers in synthetic polymers, in particular in poly-.alpha.-olefins.
