- the hydroxyl group-containing vinyl monomer is a hydroxyl group-containing unsaturated carboxylic acid monomer, a hydroxyl ether-containing vinyl ether monomer or a vinyl ketone monomer, and is preferably The diene rubber according to any one of the above (1) to (5), which is an unsaturated carboxylic acid monomer containing a hydroxyl group.
- the hydroxy group-containing unsaturated carboxylic acid monomer is a hydroxy group-containing unsaturated carboxylic acid ester, a hydroxy group-containing unsaturated carboxylic acid amide, or a hydroxy group-containing unsaturated carboxylic anhydride.
- a vinyl monomer containing an amino group and a hydroxyl group is copolymerized with a conjugated diene, or a vinyl monomer containing an amino group and a hydroxyl group is conjugated with a conjugated diene and another conjugated diene.
- a method for producing a gen-based rubber which comprises copolymerizing with a copolymerizable monomer.
- the gen-based rubber of the present invention is to provide a vulcanized rubber having excellent processability and having not only improved heat build-up but also improved tensile strength and wear resistance when silica is used as a reinforcing agent. Can be. Therefore, the gen-based rubber and the rubber composition of the present invention are useful in various applications utilizing their characteristics. For example, use as a material for tire parts such as treads, carcass, side walls, beads, etc., and as rubber products such as hoses, window frames, belts, shoe soles, anti-vibration rubber, automobile parts, etc. Use of Alternatively, it is possible to use a resin such as impact-resistant polystyrene or ABS resin as a reinforcing rubber. In particular, it is highly useful as a tread, and is suitable, for example, as a tire tread for fuel-efficient tires, as well as a tire tread for all-season tires, high-performance tires, and studless tires.
