Hot-vulcanizable tread strips for the manufacture of motor vehicle pneumatic tire treads; and block copolymers which can be used as the sole constituent of the rubber component which is the basic formulation component of said tread strips

摘要

The invention relates to hot-vulcanizable tread strips which are produced from novel vulcanizable compositions and from which the treads of pneumatic motor tires can be produced. The vulcanizable compositions are based on a rubber component which includes a special, novel rubber component based on isoprene.PPThe inventive tire treads have an excellent combination of useful properties which can be described by the following set of characteristics:PP(a) High flexibility of low temperatures, i.e., the elastic rubber state is retained even at temperatures below -30 C. (i.e., good cold- weather properties);PP(b) High vibration-damping over a wide temperature range, and thus good wet skid resistance (i.e., tread safety); PP(c) High wear-resistance, and thus long service life (i. e., economic advantages).PPThe tire treads have good all- weather characteristics, and thus the tires may be used year- round.
