Polyether Ether Ketone/Polyphenylene Sulfide Blend

Abstract

The present description discloses a polymeric composition which is a melt-processed alloy comprised of (a) a polyarylene sulfide resin, (b) a polyaryl-ether-ketone resin, and a reactive compound which results in (c) a graft copolymer of the polyarylene sulfide resin and/or the polyaryl-ether-ketone resin in addition to the starting resins. Exemplary melt-processed polymeric compositions can be made by reacting an alkoxy silane with the polyarylene sulfide resin and/or the polyaryl-ether-ketone resin to produce a graft copolymer of a portion of one or both of the resins, sufficient to render the composition uniform and homogeneous. It is normally preferred for the exemplary organosilane compound, to be an amino silane. The subject invention further reveals an insulated wire comprising (1) an electrical conductor and (2) a layer of the melt-processed alloy composition; and fiber reinforced composites comprising fibers substantially fully impregnated with the alloy polymeric composition.
