Patent ID: 8648155

Claim:
A shaped article, wherein the shaped article comprises a melt-processed, polymeric composition formed by combining (a) a linear polyarylene sulfide resin having a metal endgroup content of from about 50 ppm to about 2000 ppm and having a melt viscosity of less than 6,500 poise at 310° C. and a shear rate of 1200 1/s as measured in a capillary rheometer, (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 60% to about 90% by weight, the polyarylene sulfide resin is present in the composition in an amount from about 10% to about 40% 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 at least about 75%.
