Patent number: 4831088Abstract: Epoxide-functionalized polyphenylene ethers, which may be prepared by the reaction of various acid-functionalized polyphenylene ethers with functionalized epoxides, are useful in the preparation of polyphenylene ether copolymers. These copolymers are, in turn, useful for the compatibilization of blends of polyphenylene ethers with such other polymers as polyesters and polyamides.Type: GrantFiled: October 1, 1987Date of Patent: May 16, 1989Assignee: General Electric CompanyInventor: Paul D. Sybert

Patent number: 4806601Abstract: A method for the synthesis of polyarylene polyether (PAPE) oligomers with pendant vinyl groups is presented. Aromatic polyether sulfone (APS) and poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) backbones are used for specific examples. Terminal vinyl groups may also be provided on the APS by forming the .alpha., .omega.-di(benzyl)APS before the first step of a synthesis to form a pendant groups which step involves the chloromethylation of APS and PPO to provide oligomers with chloromethyl groups. PPO containing bromomethyl groups was obtained by radical bromination of the PPO methyl groups. Both chloromethylated and bromomethylated starting materials are converted to their phosphonium salts, and then subjected to a phase transfer catalyzed Wittig reaction to provide the pendant vinyl groups. An APS containing pendant ethynyl groups is prepared by bromination of the APS with pendant vinyl groups, followed by a phase transfer catalyzed dehydrobromination.Type: GrantFiled: December 31, 1986Date of Patent: February 21, 1989Assignee: The B. F. Goodrich CompanyInventor: Virgil Percec
