Abstract

A method for blending functionalized polyphenylene ethers made with graftable orthoester moieties, preferably the orthoester is 4-acryloyloxymethyl-2-methoxy-2-methyl-1,3-dioxolane monomer, with nucleophilic polymers, preferably polyesters, polyamides, or functionalized polyolefins. The preferred method for blending is by a one-step process, in which all reactions occur in one pass.
