Abstract
Functionalized polyphenylene ethers made with graftable orthoester moieties, preferably the orthoester is 4-acryloyloxymethyl-2-methoxy-2-methyl-1,3-dioxolane monomer. The preferred method for grafting orthoester functionality onto polyphenylene ethers is by melt grafting. Once formed, these Polyphenylene ether graft orthoesters (PPE-g-OE) are useful as compatibilizers in blends of PPE with polyesters.
