Abstract

PURPOSE: To prepare the title composition having improved low-temperature impact strength and thermoformability while keeping the excellent transparency and rigidity of polypropylene, by compounding crystalline polypropylene with an ethylene-vinyl acetate copolymer, an ethylene-propylene copolymer, etc.
CONSTITUTION: A composition composed of (A) 70W90 parts by weight of a crystalline polypropylene, (B) 2W30 parts of an ethylene-vinyl acetate copolymer, (C) 1W15 parts of an ethylene-propylene copolymer and/or ethylene-propylene- diene terpolymer, and (D) 0W2 parts of a nucleating agent. The (B) component is pref. a copolymer containing 2W8wt% of vinyl acetate and having a melt strength of ≥6 grams to attain a desirable thermoformability. The diene component of the terpolymer of the (C) component is, e.g. ethylidenenorbornene, dicyclopentadiene, etc., and the (D) component is e.g. carboxylic acids, dicarboxylic acids, their anhydrides, salts, aromatic sulfonic acid salts, esters, and inorganic salts such as talc.
