<p>A rubber mixt. (I), esp. for tyre treads, based on diene rubber(s) and also contg. 5-100 phr (pts. wt. per 100 pts. wt. rubber) finely divided pptd. silica, 0-80 phr carbon black, opt. 0.2-10 phr silane coupling agent and 0.5-20 phr non-aromatic viscosity-reducing substance (II). Component (II) is based on the elements C, H and O only; it has a domain (A) with≥2 OH gps. in the form of a 1,2- or 1,3-diol and a domain (B) with≥2 chemically linked C atoms in which neither these atoms nor their chemically linked neighbouring C atoms are substd. with oxygen. Also claimed are tyres with treads consisting at least partly of vulcanised mixt. (I).</p> |
