Abstract
A process for the preparation of a graft product of polyphenylene ether and diene rubber from a starting mixture of the two polymers is described. The process can be extended by further polymerizing an alkenyl aromatic compound such as styrene in the presence of the graft product to form a novel terpolymer. The polymers which result from the process are useful as impact resistant modifiers for various engineering thermoplastics, including polyphenylene ether resins.
