Title:
【発明の名称】複数のガラス転移温度を有するゴム状ポリマーを含むゴムブレンドから成るトレッドを有するタイヤ
Document Type and Number:
Japanese Patent JP2781791
Kind Code:
B2
Abstract:
It has been determined that certain rubbery polymers having multiple glass transition temperatures can be utilized in making tires which have improved rolling resistance, improved wet skid resistance, and outstanding tread wear. These rubbery polymers are derived from at least one conjugated diolefin monomer, have a first glass transition temperature which is between -110 DEG C and -20 DEG C and have a second glass transition temperature which is between -50 DEG C and 0 DEG C. These rubber polymers can be homopolymers of conjugated diolefin monomers, copolymers of more than one conjugated diolefin monomer, or copolymers derived from at least one conjugated diolefin monomer and at least one vinyl aromatic monomer.
