RUBBER COMPOSITION FOR TYRES WITH GOOD WET GRIP AND WINTER PROPERTIES BY TAILORING PHASE MORPHOLOGY

摘要

The present invention relates to a cross-linkable rubber composition, a cross-linked rubber composition obtained by cross-linking such a rubber composition, a method of preparing a tyre and a tyre. In a cross-linkable rubber composition the cross-linkable rubber composition comprises, per hundred parts by weight of rubber (phr): ≥ 25 phr of a first rubber, the first rubber being a solution polymerized styrene-butadiene rubber (SSBR) comprising an alkoxysilane group and a primary amino group; ≥ 40 phr of a second rubber; and ≥ 1 phr of an aliphatic or aromatic resin. The first rubber has a glass transition temperature T_g of ≥ −30°C to ≤ 0°C, the second rubber has a glass transition temperature T_g of ≥ −110°C to ≤ −60°C and the resin has a glass transition temperature T_g of ≥ 30°C.
