摘要:
This invention relates to a tire having at least one component of a silica reinforced rubber composition comprised of an emulsion polymerization derived terpolymer rubber which contain pendant hydroxyl groups, particularly derived from diene hydrocarbon and vinyl aromatic compound monomers, particularly a hydroxyalkyl methacrylate. Preferably the hydroxyalkyl methacrylate is a hydroxypropyl methacrylate (HPMA). Preferably at least one additional elastomer is blended with the terpolymer rubber. The rubber composition is prepared by blending a coupling agent therewith subsequent to the addition said silica reinforcement. Said tire component may be, for example, a tire tread.
