Rubber mixtures with functionalised diene rubbers and micro gels, a method for producing and using the same

摘要

Rubber mixture comprises at least one functionalized diene rubber with a polymer chain of repeating units based on at least one diene, optionally one or more vinyl aromatic monomers, at least one styrene/butadiene-rubber gel with a swelling index in toluene of 1-25 and a particle size of 5-1000 nm, optionally other rubbers, fillers and rubber auxiliaries. An independent claim is included for producing rubber mixture, comprising mixing at least one functionalized diene rubber with at least one styrene/butadiene rubber gel, optionally other rubbers, fillers and rubber auxiliaries in a mixing apparatus at 20-220[deg] C.
