Abstract
A paintable impact copolymer composition is produced by in-reactor blending of a xylene insoluble polypropylene fraction and a xylene soluble ethylene-propylene rubber (EPR) fraction. The composition comprises from about 5 wt. % to about 50 wt. % a xylene-soluble portion and from about 50 wt. % to about 95 wt. % a xylene-insoluble portion. The ratio of the weight average molecular weight of said xylene-soluble portion to that of said xylene-insoluble portion is from about 0.5 to about 1.8. The intrinsic viscosity of said xylene-soluble portion is from about 0.5 to about 7.0 dL/g. The xylene-soluble portion comprises from about 30 to about 70 mole percent ethylene units.
