CHLOROSULFONATED ETHYLENE-ALPHA-OLEFIN COPOLYMER COMPOSITION AND BOOT FOR JOINT PRODUCED THEREFROM

摘要

PROBLEM TO BE SOLVED: To obtain a chlorosulfonated ethylene-α-olefin copolymer compsn. which is excellent in room-temp. and low-temp. tensile characteristics and in low-temp. compression set and fatigue resistance and to obtain a boot for joint produced therefrom. SOLUTION: This compsn. is prepd. by compounding 100 pts.wt. chlorosulfonated ethylene-α-olefin copolymer with 0.05-3 pts.wt. thiuram compd., 0.5-5 pts.wt. bismaleimide compd., 0.1-5 pts.wt. nickel dialkylcarbamate, and 0.5-10 pts.wt. diarylmonoamine compd. The boot for joint is produced by molding and vulcanizing the compsn.
