Epoxy-functionalized polyphenylene ethers
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- alpha -olefin. The blending reaction takes place at a temperature in the range of about 250-300 DEG C, and the a...

| description | 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- alpha -olefin. The blending reaction takes place at a temperature in the range of about 250-300 DEG C, and the amount of glycidyl acrylate employed is about 2.5-5.0% by weight based on polyphenylene ether. The products are characterized by a gel content of less than 5% by weight. They form copolymer-containing compositions having excellent properties upon melt blending with linear polyesters such as poly(butylene terephthalate). |
