Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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). 2. The rubber mixture according to claim 1 , wherein the pale-coloured filler B) comprises at least one silica. 3. The rubber mixture according to claim 1 , further comprising at least one vulcanizing agent and/or at least one vulcanization accelerator. 4. The rubber mixture according to claim 1 comprising, based on 100 parts by weight of component A): 5 to 300 parts by weight of the one or more pale-coloured fillers B), and 0 to 150 parts by weight of one or more further rubber additives E). 5. The rubber mixture according claim 4 , wherein the ratio by weight of component C) to component 0) is from 10:1 to 1:20. 6. The rubber mixture according to claim 1 , wherein the ratio by weight of component C) to component D) is from 10:1 to 1:20.
