Abstract
The present invention relates to a sulfur-crosslinkable rubber composition comprising a filler component in an amount in the range of 1 to 350 phr, and at least one graft copolymer having a modified diene rubber backbone and one or more oligomeric side chains grafted to the modified diene rubber backbone, wherein the oligomeric side chains are obtained through reversible addition fragmentation chain transfer polymerization of a monomer composition, and wherein the monomer composition comprises at least one polar monomer.

Sulfur-crosslinkable rubber composition comprising:
- a filler component in an amount in the range of 1 to 350 phr,
- at least one graft copolymer having a modified diene rubber backbone and one or more oligomeric side chains grafted to the modified diene rubber backbone, and wherein the oligomeric side chains are obtained through reversible addition fragmentation chain transfer polymerization of a monomer composition, and wherein the monomer composition comprises at least one polar monomer,
- wherein the monomer composition comprises at least one methacrylate monomer, as at least one polar monomer, and the monomer composition comprises at least one aromatic hydrocarbon monomer with a vinyl moiety, as at least one unsaturated hydrocarbon monomer,
- wherein the at least one methacrylate monomer includes 2-(dimethylamino)ethyl methacrylate and the at least one aromatic hydrocarbon monomer with a vinyl moiety includes styrene, the 2-(dimethylamino)ethyl methacrylate and styrene being present in a combined amount of 50% or more by weight, with respect to the weight of the monomer composition.
