The invention relates to a sulfur-crosslinkable rubber mixture, in particular for the tread of pneumatic vehicle tyres, comprising at least the following components: 10 to 90 phr (parts by weight, based on 100 parts by weight of all rubber in the mixture) of at least one solid, solution-polymerized, functionalized butadiene rubber, the functionalization enabling interaction with polar fillers, and at least 90 phr (parts by weight, based on 100 parts by weight of all rubber in the mixture) of at least one solid, solution-polymerized, functionalized butadiene rubber; the invention relates to a rubber composition comprising-at least one polar filler,-at least one further diene rubber,-at least one liquid modified diene polymer A having a weight average molecular weight Mw through GPC of 500 to 50000 g/mol, preferably 2000 to 10000 g/mol, where the modification enables interaction with the polar filler and is present along the polymer backbone, and-10 to 300 phr of at least one silica,-at least one further diene rubber,-at least one liquid modified diene polymer A having a weight average molecular weight Mw through GPC of 500 to 50000 g/mol, preferably 2000 to 10000 g/mol, and-10 to 300 phr of at least one silicon dioxide.
本发明涉及一种硫可交联的橡胶混合物,尤其是用于充气车辆轮胎的胎面,其至少包含以下成分:‑10至90phr(重量份,基于该混合物中的100重量份的所有橡胶)的至少一种固体的溶液聚合的官能化丁二烯橡胶,其中官能化使能够与极性填料相互作用,‑至少一种另外的二烯橡胶,‑至少一种液体的改性的二烯聚合物A,其具有通过GPC的500至50000g/mol、优选2000至10000g/mol的重均分子量Mw,其中改性使能够与极性填料相互作用并且是沿着聚合物主链存在,以及‑10至300phr的至少一种二氧化硅。
