Abstract

PURPOSE: To provide a diene rubber composition of improved flow characteristics and processability in an uncured state and capable of affording cured products having improved hardness and bonding to metallic material, which comprises a specific maleic anhydride-added liquie polyisoprene rubber and a solid diene rubber.
CONSTITUTION: The objective rubber composition comprising (A) 5W45(pref. 15W30wt% of a liquid rubber prepared by adding 0.1W15 (pref. 0.5W10)mol%, based on the isoprene monomer unit, of maleic anhydride (or its derivative) to a liquid polyisonprene rubber having an amount of cis-1,4 linkage ≥70mol% (pref. ≥80mol%) and a molecular weight of 8,000W100,000 (pref. 15,000W55,000), and (B) 95W55 (pref. 85W70)wt% of a solid diene rubber, preferably a natural rubber having a Mooney viscosity ≥35 (pref. 90W130). For manufacturing the composition, a kneading operation may be carried out using a roll mill, etc.
USE: For steel radial tires, steel-reinforced conveyor belts, etc.; for shoes with addition of a white filler.
