VISCOELASTICITY IMPROVER FOR RUBBER AND RUBBER COMPOSITION CONTAINING IT

摘要

PROBLEM TO BE SOLVED: To provide a viscoelasticity improver for a silica-formulated rubber composition to reduce Mooney viscosity and improve viscoelastic characteristics. SOLUTION: This viscoelasticity improver for rubber comprises a polymer having a side chain containing a polyether and an alkoxysilane, or a polymer having a side chain containing the polyether, the alkoxysilane and a double bond.
