Abstract:
1. A shaped polymer article comprising: a blow molded hollow member including an interior surface and an exterior surface and having a wall thickness between the interior surface and the exterior surface, the hollow member being made from a fiber reinforced polymeric composition comprising on a weight percent basis: a) a linear polyphenylene sulfide having a melt viscosity of from about 20 Pa.s to about 500 Pa.s; b) a branched polyphenylene sulfide, the weight ratio of the branched polyphenylene sulfide to the linear polyphenylene sulfide being from about 1:5 to about 1:60, the linear polyphenylene sulfide and the branched polyphenylene sulfide being present in the composition in an amount of at least about 35% by weight; c) reinforcing fibers present in the composition in an amount from about 10% to about 50% by weight; d) a compatibilizer present in the composition in an amount from about 0.1% to 5% by weight; e) a polytetrafluoroethylene present in the composition in an amount from about 0.01% to about 3% by weight; and f) a reactive impact modifier present in the composition in an amount from about 0.5% to about 10% by weight; wherein the composition has a melt viscosity of at least about 3500 poise measured at 316° C. and at 400 s
