Abstract
Polystyrene having a high storage modulus is blended with a polyolefin, and the blend is converted to a mixed melt which is caused to flow and then a cooled and solidified to form a substantially solid two phase composite. The high storage modulus polystyrene provides particularly good results. Especially good properties are achieved at about 35% polystyrene by weight. Either or both components may be recycled materials and may incorporate minor amounts of other plastics as contaminants.
