Abstract:
1. A melt-processed, polymeric composition formed by combining (a) a polyarylene sulfide resin having a metal endgroup content of at least about 270 ppm, (b) a polyaryl-ether-ketone resin, and, a reactive compound wherein (c) a graft copolymer of (a) and/or (b) is formed rendering the composition homogeneous, wherein the polyaryl-ether-ketone resin is present in the composition in an amount from about 15% to about 40% by weight, the polyarylene sulfide resin is present in the composition in an amount from about 60% to about 85% by weight, and the reactive compound is an alkoxy silane present in the composition in an initial amount from about 0.2% to about 2% by weight, wherein the composition has a tensile strength retention after 500 hours at 230° C. of from about 75%-103%.
