Abstract
A highly filled, mechanically strong and impact resistant composition is prepared by combining about 25-80% polyolefin with about 10-60% rigid inorganic particulate filler of aspect ratio less than 15, thoroughly blending using high shear equipment until the flexural modulus is at least 1.25 times that of the base polyolefin and subsequently incorporating therein, using low or non-shear techniques, about 10-45% fibrous reinforcement of length at least 11/2 inches.
