ABSTRACT:
Polyphenylene oxide is conveniently blended with conjugated diene-monovinylarene copolymers by using a mixed solvent of aromatic and paraffinic/cycloparaffinic hydrocarbons; preferably a polyphenylene oxide solution in an aromatic solvent is added to the copolymer cement prior to polymer recovery but after monomer polymerization is essentially complete.
