Abstract
This invention provides a diene rubber capable of yielding a vulcanized rubber having improved heat build-up, tensile strength and abrasion resistance, processes for preparing the same, and rubber compositions containing the same. The diene rubber is composed of 40 to 99.99% by weight of conjugated diene monomer units, 0 to 50% by weight of aromatic vinyl monomer units, and 0.01 to 20% by weight of vinyl monomer units containing a tertiary amino group which is at least partially quaternized with a hydrocarbon radical, and has a Mooney viscosity (ML,, 100° C.) of 10 to 200.
