摘要: PROBLEM TO BE SOLVED: To provide a rubber composition effective for lowering the viscosity of an unvulcanized while keeping impact resilience and breakage property vulcanized composition, prolonging scorch time to improve workability reducing release volatile alcohol pneumatic tire produced by using composition. SOLUTION: The contains component, silica organic silicon compound expressed average compositional formula (1) (in formula, R 1 2 are each independently 1-4C univalent hydrocarbon group; 3 is 1-18C 4 , 5 6 1-15C bivalent m 1-4 in terms value; n 2-4 q 0-3; u 0 or 1; p r 0, 2; s t >0 ≤3 value), COPYRIGHT: (C)2008,JPO&INPIT
