摘要：
An opacified stretched molded product has a total light transmittance of 50% or less and a density of 0.89 or less and comprimises a composition containing 100 parts by weight of polypropylene and 3 to 40 parts by weight of a cyclopentadiene petroleum resin, said molded product being a product stretched in at least one direction. The invention also provides a resin composition comprising 100 parts by weight of a crystallline polypropylene and 30 to 40 parts by weight of a copolymer resin comprising a copolymer of a cyclopentadiene compound and an aromatic hydrocarbon or a hydrogenated product thereof, and a stretched molded product therefrom. The invention also provides processes for producing the opacified molded products.
