Abstract
A polyolefin plastic composition having improved transparency and reduced molding shrinkage, which consists essentially of at least one polymer or copolymer of an aliphatic monoolefin and dibenzylidene sorbitol, the proportion of the dibenzylidene sorbitol being 0.1 to 0.7% by weight based on the total weight of the composition.
Claims4
A polyolefin plastic composition having improved transparency and reduced molding shrinkage, which consists essentially of at least one homopolymer or copolymer of an aliphatic monoolefin containing 2 to 6 carbon atoms which has an average molecular weight of about 10,000 to 200,000, said copolymer made by polymerizing said monoolefins with one another and dibenzylidene sorbitol, the proportion of the dibenzylidene sorbitol being 0.1 to 0.7% by weight based on the total weight of the composition.
