Abstract:
A thermoplastic resin composition having enhanced shear sensitivity consisting of(a) from 50 to 97 percent by weight of a shear enhancing alkylene aryl polyester copolymers having metal sulfonate units represented by the formula IA: ##STR8##or the formula IB:(M.sup.+n O.sub.3 S).sub.d -A-(OR""OH).sub.pwhere p=1-3, d=1-3, p+d=2-6, n=1-5, M is a metal, and A is an aryl group containing one or more aromatic rings where the sulfonate substituent is directly attached to an aryl ring, R"" is a divalent alkyl group and the metal sulfonate group is bound to the polyester through ester linkages;(b) from 3% to about 50% by weight of a glass fiber filler to reinforce and stiffen the composition and form a reinforced molding composition.
