RUBBER COMPOSITION, CROSSLINKABLE RUBBER COMPOSITION AND CROSSLINKED ARTICLES

摘要

Rubber composition containing (1) a diene rubber, (2) a highly saturated rubber and (3) a block copolymer constituted of one or more diene polymer blocks (A) and one or more hydrogenated diene polymer blocks (B). Rubber composition containing (1) a diene rubber, (2) a highly saturated rubber and (3) a block copolymer constituted of one or more diene polymer blocks (A) and one or more hydrogenated diene polymer blocks (B). The rubber composition has a primary structure of (A-B) x'(A-B) x- A, or B - (A-B) x. x : integer = one or greater The amount of the block copolymer (3) is 0.1 - 25 pts wt per 100 pts wt of the total amount of the rubbers (1) and (2).
