摘要： A vulcanizate prepared by a method comprising introducing an elastomer, a filler, and a polar polysulfide crosslinking agent to form a masterbatch and introducing a curative to the masterbatch to form a vulcanizable composition. Vulcanizing the composition to graft the polar group from the crosslinking agent onto an elastomer to increase the hydrophilicity of the composition.

摘要： Disclosed herein are a functionalized diene monomer-containing polymer containing first and second functionalizing groups, processes for preparing the functionalized polymer, and rubber compositions containing the functionalized polymer. The functionalized polymer contains polymer chains comprises of at least one conjugated diene monomer optionally in combination with at least one vinyl aromatic monomer wherein each polymer chain is functionalized at its chain end with at least the first functionalizing group and is coupled via the first functionalizing group to the second functionalizing group.
