ABSTRACT:
A hydrocarbon resin/polyphenylene ether comblike polymer and mixtures of these with polyphenylene ethers is disclosed. The comblike polymers are obtained by oxidative coupling reactions of ortho-substituted phenols and hydrocarbons with side groups (on the hydrocarbons) of formula ##STR1## where R.sub.5 and R.sub.6 are each halogen, phenyl, or n-alkyl with 1-4 C atoms, and R.sub.7 is a hydrogen atom, a halogen atom, a phenyl group or an n-alkyl group with 1-C atoms.
