Patent ID: 8357739

Claim:
A thermoplastic composition, comprising: a base polymer; wherein said base polymer is polyimide, polyphenylene sulfide, polyphenylene ether, polyethersulfone, polysulfone, polyetheretherketone, polycarbonate, polyphenylene oxide, polyester, polyamide, polystyrene, mixtures, copolymers, reaction products, or blends comprising at least one of the foregoing polymers an irradiated fluoropolymer; wherein the fluoropolymer is present in the range from 3 to 50% by weight of the thermoplastic composition; and a fluoride scavenger; wherein the fluoride scavenger is an organic calcium salt, calcium oxide, minerals with calcium oxide; or a mixture comprising at least one of the foregoing fluoride scavengers; wherein the fluoride scavenger is effective to produce a fluoride level of below 40 micrograms per gram of the thermoplastic composition; and wherein said composition has a lower fluoride ion level relative to a composition consisting of the base polymer and the fluoropolymer.
