Patent ID: 6841629

Claim:
A process for preparing a modified polyphenylene ether resin, which comprises: reacting a mixture of 100 parts by weight of (A) a polypheylene ether having a main chain structure of the following formula (1) wherein R 1 and R 4 each independently represents hydrogen, a primary or secondary lower alkyl, a phenyl, an aminoalkyl or a hydrocarbonoxy, and R 2 and R 3 each independently represents hydrogen, a primary or secondary lower alkyl or phenyl, and 0.01 to 10 part by weight of (B) a modifier selected from the group consisting of conjugated non-aromatic diene compounds, dienophilic compounds having one dienophile group and precursors of the diene or dienophilic compounds at a temperature not lower than a room temperature and not higher than the melting point of (A) wherein the reaction to obtain the modified polyphenylene ether resin is carried out in a state where the polyphenylene ether is a solid.
