Abstract
A complex of polyphenylene ether resin and methylene chloride obtained by polymerizing a phenol in methylene chloride and then cooling the mixture to cause the complex to precipitate, is mixed with a vinyl aromatic compound, e.g., styrene monomer, heated to decompose the complex and remove methylene chloride from the blend, and thereafter the vinyl aromatic compound is polymerized. The products are useful as molding resins and the like.
