Title:
RUBBER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/1994/022951
Kind Code:
A1
Abstract:
A rubber composition suitable as an all-weather tire material having well-balanced wet-skid resistance, low-temperature characteristics and fuel consumption. The composition comprises a random copolymer A with a glass transition temperature of -20 �C or above, a random copolymer B with a glass transition temperature of -50 �C or below, and a block copolymer C comprising a copolymer A block and a copolymer B block. The copolymers A, B and C are produced by copolymerizing an aromatic vinyl compound with a conjugated diene in the presence of a catalyst based on an alkali metal.
