Vulcanisable rubber mixture, vulcanised material, and rubber product

A vulcanizable rubber compound comprising:

• a) one or more diene rubbers,
• b) one or more fillers selected from the group consisting of silicas,
• c) one or more polyetheramines in a combined part by weight in the range from 0.1 to 10 phr,
• the polyetheramines being selected from the group consisting of polyetheramines of formula I):
• where R1, R2, R3 and R4 are each independently hydrogen or either branched or unbranched hydrocarbon radicals having 1 to 10 carbon atoms, where m is 0 or 1, where R5 and R6 are each independently either branched or unbranched hydrocarbon chains having 1 to 10 carbon atoms,
• where X is a polyether chain of formula II):
• where x is in the range from 2 to 30, where R7i and R8i in each monomer unit i are, in each case, each independently and independently of the other monomer units in the polyether chain hydrogen or hydrocarbon radicals having 1 or 2 carbon atoms, and
• d) one or more liquid polybutadienes, the one or more liquid polybutadienes having a number-average molar mass Mn, measured by GPC, in the range from 500 to 20 000 g/mol.
