摘要

MOLDED CALCIUM CARBONATE FILLEDPROPYLENE RESIN COMPOSITESABSTRACT OF THE DISCLOSUREA method for increasing impact properties of calciumcarbonate filled propylene resin composites, particularly impactproperties at low temperatures, which comprises admixing criti-cally sized particles of propylene homopolymer and copolymerresins and calcium carbonate filler to form uniform, preferablypowdery, blends particularly suitable for such shaping operationsas injection molding.
