1. A process for the preparation of a composition which comprises:
- (a) a polyphenylene oxide resin that is capped with a compound selected from the group consisting of acid halides, acid anhydrides and ketenes; and
(b) an alkenyl aromatic resin;
said process comprising forming a mixture of a capped polyphenylene oxide in an alkenyl aromatic monomer and thereafter heating said mixture for a sufficient period of time at an elevated temperature to form said composition.

Abstract
There is described a process for making a composition of a capped polyphenylene oxide and an alkenyl aromatic resin which is based on the thermal polymerization of an alkenyl aromatic monomer in the presence of a capped polyphenylene oxide.

8. A process for the preparation of a composition which comprises:
-
(a) 10-90 parts by weight of poly(2,6-dimethyl-1,4-phenylene oxide) that is capped with a compound selected from the group consisting of acid halides, acid anhydrides and ketenes; and (b) 90-10 parts by weight of polystyrene resin;
said process comprising forming a mixture of which consists of a capped polyphenylene oxide and styrene monomer and heating said mixture for a period of time at a temperature that is sufficient to cause the styrene monomer to polymerize and form said composition. - View Dependent Claims (9, 10, 11)
