HYDROGENATED BLOCK COPOLYMER PELLETS POLYOLEFIN RESIN COMPOSITION AND MOLDED BODY OF SAME

摘要

The purpose of the present invention is to provide hydrogenated block copolymer pellets which are free from blocking with each other and formed into a molded body that has excellent transparency flexibility bleed out properties and low combustion ash content. The hydrogenated block copolymer pellets contain 100 parts by mass of a pellet molded body that is formed of a hydrogenated block copolymer (A) and 0.01 1.5 parts by mass of flour that is formed of a polyethylene powder (B). The hydrogenated block copolymer (A) has at least one polymer block (a) that is mainly composed of a vinyl aromatic monomer unit and at least one polymer block (b) that is mainly composed of a conjugated diene monomer unit and has a total of the 1 2 bond content and the 3 4 bond content of 40 90% before hydrogenation. The hydrogenated block copolymer (A) has a hardness of 30 67°; the content of the polymer block (a) in the hydrogenated block copolymer (A) is 5 30% by mass; and the polyethylene powder (B) has a number average molecular weight of 15000 or less an average particle diameter of 1 15 µm and a repose angle of 45 70°.
