RUBBER COMPOSITION, ITS VULCANIZED RUBBER, AND TIRE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition which exhibits excellent performance on ice and can satisfy good dry steering stability and abrasion resistance, to provide a vulcanized rubber, and to provide a tire using the same. SOLUTION: This rubber composition is characterized by dispersing a non-linear fine particle-containing resin containing fine particles having Mohs hardness of≥2 in a rubber matrix and containing the fine particle-containing resin in a matrix and containing the fine particles in such an amount as >50 to 900 pts.mass per 100 pts.mass of the resin. The vulcanized rubber comprising the rubber composition in which the viscosity of the resin and the viscosity of the rubber matrix are suitably selected in response to the maximum vulcanization temperature. The vulcanized rubber is used for tires. COPYRIGHT: (C)2006,JPO&NCIPI
