Mixtures composed of functionalized diene rubbers with trimethylolpropane and fatty acid, a process for production thereof and use thereof

摘要

The invention relates to functionalized diene rubbers with trimethylolpropane and fatty acid, to a process for production there of and use thereof for the production of wet-skid-resistant and low-rolling-resistance motor-vehicle tire treads with high abrasion resistance.

主权项

1. A vulcanizable rubber mixture comprising:
A) at least one diene rubber functionalized with carboxy groups and/or hydroxy groups and/or with their salts, wherein the functionalized diene rubber is composed of 40 to 100% by weight of units derived from 1,3-butadiene, and 0 to 60% by weight of units derived from styrene, and a proportion of bonded functional groups and/or of their salts is 0.02 to 5% by weight, based on 100% by weight of the diene rubber, B) at least one pale-coloured filler, C) trimethylolpropane, and D) at least one fatty acid, wherein the sum total of components C) and D) is 0.1 to 20 parts by weight, based on 100 parts by weight of component A).
