Rubber composition of two diene rubbers
摘要:
A diene rubber (iii) can be obtained by mixing in a solution state:a modified styrene-butadiene rubber (i) having a weight-average molecular weight of 150,000-500,000, obtained by reacting a diene polymer having a bound active metal in the molecule, with a modifier such as N-methyl-.epsilon.-caprolactam or the like, anda branched styrene-butadiene rubber (ii) having a weight-average molecular weight of 800,000 or more.This diene rubber (iii) and a rubber composition comprising the diene rubber (iii) and other diene rubber (iv) have superior processability when unvulcanized and give a vulcanized rubber having improved abrasion resistance, resiliency and low-temperature properties.
