Abstract

The rubber mixtures containing modified rubber gels according to the invention prepared from at least one rubber gel modified with compounds containing sulphur and reactive towards C.dbd.C double bonds and at least one rubber containing double bonds are preferable suitable for the production of vulcanizates which have an unusually strong reinforcing action in rubber vulcanizates. The vulcanisates furthermore exhibit unusually low dynamic damping at relatively elevated temperatures. They are thus particularly suitable for the production of low rolling resistance motor vehicle tire treads.
