摘要

A sulfur crosslinkable rubber composition (I) for the production of tire treads preferably for vehicles having anti-skid braking systems (ABS), comprises polyisoprene, a styrene-butadiene copolymer, (optionally) polybutadiene and at least carbon black as filler, in addition to other conventional additives. A crosslinkable sulfur composition (I) comprises: (A) 5-50 phr (parts per 100 wt. (I)) cis-1,4-polyisoprene; (B) 0-90 phr solution- polymerized styrene/butadiene copolymer; (C) 0-70 phr polybutadiene; (D) up to 50 phr an emulsion polymerized styrene-butadiene copolymer, whereby at a minimum content of (D) of 25 phr, (I) contains 2-10 phr abietic acid, dehydro abietic acid, dihydroabietic acid, tetrahydroabietic acid and/or their isomers; and (E) at least 50 phr silicic acid, whereby the ratio of silicic acid to carbon black is at least 5:1. An Independent claim is included for inflated vehicle tires having a tread produced from the composition (I).
