Abstract: The vulcanizable rubber mixture according to this invention is used for rubber products in particular vehicle tires and vehicle tire treads, but also technical rubber products like belts on conveyor systems, technical hoses, vibration dampers and impact dampers, or wire coatings. All these products benefit from the improved processability that is achieved with the invention in that the mixture comprises a polymer represented by the formula F1-A-F2, or a mixture of F1-A-F2 with an astral or radial coupling product of F1-A-units, coupled by a multivalent coupling agent; wherein F1 represents a terminal functionalization of the polymeric chain, F2 represents a terminal functionalization different from F1; and A represents the polymeric chain of a polymer formed by the copolymerization between one or more conjugated dienes with one or more aromatic vinyl monomers.

Abstract: A vulcanizable rubber mixture and its use for rubber products, which need good grip in wet or icy conditions, in particular vehicle tires and vehicle tire treads, but also technical rubber products like belts on conveyor systems, technical hoses, or vibration dampers and impact dampers. The vulcanizable rubber mixture includes from 10 to 100 phr of a block copolymer functionalized at least at one chain end (terminally) for binding to fillers, at least one filler and, optionally, additives. The block copolymer contains a statistically or microsequentially polymerized copolymer comprising a conjugated diene and an aromatic vinyl compound, and has, polymerized onto at least one end of the main chain, 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.

Abstract: 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 tires and vehicle tire treads, but also technical rubber products like belts on conveyor systems which can have exposure to weathering, technical hoses, or vibration dampers and impact dampers.

Abstract: The invention relates to a rubber mixture that can be cross-linked by sulphur and contains, in order to achieve low-temperature flexibility and high-temperature rigidity, at least one diene rubber, between 5 and 150 phr (weight parts in relation to 100 weight parts of the total rubber mass) of at least one type of soot with an iodine adsorption index >65 g/kg and a DBP index >90 cm3/100 g, and between and 150 phr of a type RAE (residual aromatic extract) crude oil fraction as a softener. The weight ratio of the soot to the crude oil fraction in the mixture is 1:1 to 1:10.
