More Information
Summary:Raw elastomeric composition comprising: (a1) from 30 to 90% by weight of a partially hydrogenated vinylarene- conjugated diene random elastomeric copolymer; (a2) from 10 to 70% by weight of one or more diene rubbers; (b) from 10 to 150 phr of silica; (c) from 0.1 to 20 phr of a coupling agent based on silane; (d) from 0.1 to 10 phr of a vulcanization agent; the above composition being characterized in that the partially hydrogenated vinylarene -conjugated diene random copolymer has a structure which has nodes statistically distributed in the macromolecule, from which polymeric chains branch out, the bond between said nodes and said branches being a carbon- carbon bond.
