Title:
VULCANIZABLE RUBBER COMPOSITION
Document Type and Number:
Japanese Patent JP3255687
Kind Code:
B2
Abstract:
PURPOSE: To prepare the title compsn. excellent in strengths, oil resistance, adhesion to fiber, etc., by mixing a specific higher α-olefin copolymer with a (hydrogenated) nitrile rubber in a specified wt. ratio.
CONSTITUTION: A higher a-olefin copolymer is produced by copolymerizing a 6-20C higher a-olefin (e.g. octene-1), an α,ω-diene of formula I (wherein n is 1-3; and R1 and R3 are each H or 1-8C alkyl)(e.g. 1,4-hexadiene), and a nonconjugated diene of formula II (wherein n is 1-5; R3 is 1-4C alkyl; and R4 and R5 are each H or 1-8C alkyl provided that they are not simultaneously H)(e.g. 4-methyl-1,4-hexadiene). The title compsn. is prepd. by mixing the copolymer with a nitrile rubber and/or a hydrogenated nitrile rubber in a wt. ratio of (5:95)-(95:5).
