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.
