THERMOPLASTIC ELASTOMER COMPOSITION AND MOLDED ARTICLES THEREOF

摘要

A thermoplastic elastomer composition containing 100 wt. parts, in total, of an ethylene- alpha -olefin copolymer rubber and a polyolefin resin, and 0.1 to 150 wt. parts of at least one hydrogenated diene polymer having a hydrogenation degree of at least 70 % selected from the group consisting of hydrogenated conjugated diene polymers and hydrogenated products of random copolymers comprising conjugated dienes and aromatic vinyl compounds in which the content of the aromatic vinyl compound units is 25 wt. % or less, in which the composition has a complex dynamic viscosity eta * (1) of 1.5 x 10<5> poise or less, and a Newtonian viscosity index n of 0.67 or less. This composition provides molded articles which are not whitened on bending, and has good flexibility.
