PROPYLENE RANDOM COPOLYMER COMPOSITION

摘要

A propylene random copolymer composition which contains a mixture of 0.05-2.7% by weight of a crystalline propylene homopolymer (A) and 97.3-99.95 by weight of a random copolymer (L) of propylene and at least one .alpha.-olefin other than propylene which copolymer has a bound propylene content of 40-85% by weight and a Mw/Mn of not more than 5.5 meets both of the two mutually conflicting requirements of further improving the transparency inherent to polypropylene sheet and film, and attaining excellent solvent resistance.-
