| abstract |
The present invention provides a rubber compositionnwhich has satisfactory processability and dimensionnstability, exhibits excellent tensile strength and wearingnresistance, and the like when vulcanized and is useful asna material for an industrial product such as a rubber roll,na grinding roll, a belt, a hose and a rubber-coated fabric,na shoe part for example of a transparent shoe, a tire ofna large-sized or small sized car such as a tread and a sidenwall and a sanitary material such as a contraceptive rubbernor the like. A rubber composition of the inventionncomprises (1) a crosslinked rubber particle containing asnrepeating units (a) 39.89 to 79.89 % by weight of anconjugated diene unit such as 1,3-butadiene or the like,n(b) 20 to 60 % by weight of an aromatic vinyl unit such asnstyrene, (c) 0.01 to 10 % by weight of a monomer unit havingnat least two polymerizable unsaturated group such asndivinylbenzene, and the like, and (d) 0.1 to 30 % by weightnof a monomer unit having one polymerizable unsaturatedngroup and an amino group such as vinylbenzylmethylamine,nand the like and (2) a conjugated diene/aromatic vinylncopolymeric rubber such as styrene-butadiene copolymericnrubber and the like. |
