Abstract

A sulfur-crosslinkable rubber blend which includes from 60 to 100 phr of at least one butadiene rubber and 51 phr or more of at least one hydrocarbon resin which is built up to the extent of 30 to 100 wt. % from aromatic monomers. In some aspects the sulfur-crosslinkable rubber has from 51 to 300 phr of the at least one hydrocarbon resin which is built up to the extent of 30 to 100 wt. % from aromatic monomers, and in some cases, the hydrocarbon resin is built up to the extent of 30 to 100 wt. % from at least one aromatic monomer from the group consisting of alpha-methylstyrene and/or styrene and/or vinyltoluene and/or indene and/or coumarone and/or methylindene and/or methylcoumarone.
