<p>PROBLEM TO BE SOLVED: To obtain a vessel which is transparent without cloudiness, accompanied by no odor and can be suitably used for food products and medical purposes, by combining a crystalline propylene polymer with a specific block copolymer. SOLUTION: A crystalline propylene polymer of which melting point is 120-145 deg.C, in an amount of 95-80wt.% is blended with 5-20wt.% of a hydrogenated diene copolymer which comprises a (A)-(B) block copolymer containing (A) a vinyl aromatic compound polymer block and (B) a conjugated diene polymer or a vinyl aromatic compound - a conjugated diene random copolymer block, or if necessary (A)-(B)-(C) block copolymer, additionally containing (C) taper block in which the vinyl aromatic compound in the vinyl aromatic compound and the conjugated diene is gradually increased, or (A)-(B)-(A) where the weight ratio of the vinyl aromatic compound and/or the conjugated diene is (5-60)(95-40).</p> |
