Patent number: 4517341Abstract: By synthesizing a polyphenylene oxide using a catalyst comprising a primary or secondary amine and/or a manganese compound, the same can be grafted to an unsaturated compound such as an unsaturated rubber at high yield. A process for so modifying an unsaturated compound such as an unsaturated rubber and the product obtained thereby are disclosed.Type: GrantFiled: October 24, 1983Date of Patent: May 14, 1985Assignee: General Electric CompanyInventor: Dwain M. White

Patent number: 4491649Abstract: Polyphenylene ether resins impact modified with a rubbery impact modifier such as an ABA block copolymer or a polyolefin is made more processable by further compounding with a moderate amount of an aromatic polycarbonate. The compositions exhibit markedly high impact strength and high heat distortion temperature characteristics.Type: GrantFiled: December 1, 1983Date of Patent: January 1, 1985Assignee: Borg-Warner Chemicals, Inc.Inventors: John C. Falk, Ronald L. Jalbert, Klementina F. Khait

Patent number: 4483953Abstract: Polyphenylene ether resins and resin compositions in admixture with trineopentylene diphosphite as a thermal oxidative stabilizer are described. These can be used with or without an impact modifier for the polyphenylene ether resin. An additional benefit is that the resins and compositions exhibit a higher heat distortion temperature.Type: GrantFiled: September 12, 1983Date of Patent: November 20, 1984Assignee: General Electric CompanyInventor: Robert J. Axelrod

Patent number: 4480073Abstract: Thermoplastic blends having superior capability and homogeneity comprising a poly(phenylene oxide) resin and a resin of poly(methyl ethenyl benzene) isomers in which the predominant isomer is 1-methyl-4-ethenyl benzene, are disclosed. The poly(phenylene oxide) resin can contain substituted phenylene units and the poly(methyl ethenyl benzene) resin can be a polymer of solely methyl ethenyl benzene isomers, or a random, block or graft copolymer comprising 50 weight percent or more of methyl ethenyl benzene iosmers and up to 50 weight percent of other ethylenically unsaturated monomers.Type: GrantFiled: July 13, 1981Date of Patent: October 30, 1984Assignee: Mobil Oil CorporationInventor: Robert V.
