| 5281667 | Epoxy-functionalized polyphenylene ethers of low gel content, method for their preparation, and copolymer-containing compositions prepared therefrom Epoxy-functionalized polyphenylene ethers are prepared by melt blending a polyphenylene ether with glycidyl acrylate in the presence of a lubricant such as at least one hydrogenated poly--olefin. The blending reaction takes place at a temperature i... | 01/25/1994 |
| 5247006 | Polyphenylene ether-graft-orthoester copolymer blends and method of preparation 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... | 09/21/1993 |
| 5231197 | Method for producing ethylenically unsaturated graftable orthoesters Ethylenically unsaturated graftable monomers are prepared by reacting hydroxy substituted orthoesters with electrophilic reagents, an alkaline reagent, and a phase transfer catalyst.
