VULCANIZABLE RUBBER MIXTURE AND ITS USE FOR RUBBER PRODUCTS

摘要

The invention relates to a vulcanizable rubber mixture and to its use for rubber products which need good grip in wet conditions or in icy conditions, in particular vehicle tyres and vehicle tyre treads, but also technical rubber products like belts on conveyor systems which can have exposure to weathering, technical hoses, or vibration- and impact-dampers. The vulcanizable rubber mixture comprises at least one block copolymer functionalized at least at one chain end (terminally) for binding to fillers, at least one filler and, if appropriate, additives and is characterized in that the mixture comprises from 10 to 100 phr of a statistically or microsequentially polymerized copolymer comprising a conjugated diene and an aromatic vinyl compound, and which has, polymerized onto at least one end of said main chain copolymer, a terminally functionalized block of different structure to the main chain, which structure is homopolymeric or copolymeric, from 5 to 250 monomer units long, and composed of at least one of the mers of the main chain copolymer, with the provisio that the glass transition temperatures on the one hand of the main chain and on the other hand of the terminal block or block polymer are different.
