THERMOPLASTIC ELASTOMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition of excellent strength.

SOLUTION: The thermoplastic elastomer composition is obtained by feeding 100 pts.wt. of the total of (A) 10-70 pts.wt. of an ethylene-α-olefin-nonconjugated polyene copolymer rubber and (B) 30-90 pts.wt. of an ethylene-α-olefin-based copolymer rubber and a crosslinking agent to a melt kneader followed by conducting a dynamic heat treatment of components A and B in the presence of the crosslinking agent.
