ABSTRACT:
By synthesizing a polyphenylene oxide using a catalyst comprising a primary or secondary amine and/or a manganese compound, the same can be grafted to an unsaturated compound such as an unsaturated rubber at high yield. A process for so modifying an unsaturated compound such as an unsaturated rubber and the product obtained thereby are disclosed.
