| The oil-filled styrene (alpha-methyl styrene)-butadiene SBR 1712 Rubber is produced by emulsion copolymerization of styrene and butadiene at 4-8 C, using as an emulsifier a mixture of disproprortionated liquid rosin, that is resinous and fatty acids of natural origin based. The technological process and methodics of production eliminate in synthesis processes using and formation of nitrose compounds. The diethylthydroxylamim is used in polymerization as a stopper. The polymer coagulates in a system “salt+acids” and does not contain any side inclusions of the structural and wet polymer. It is well mixing with different ingredients of rubber compounds and is easily treated on the simple rubber production equipment, is quite compatible with different rubbers of general use, has a low cost. In mixing with SBR 1500 at 1:1 rate the product will be of higher hardness, will grow tires abrasion resistance and will make bigger its running time up to 10%. Application: The SBR1712 is general purpose rubber. It is widely used in tire, rubber technical, shoe, cable and other industries for production of automobile tires and tubes, wide assortment of rubber technical articles, white and colour shoes, cable castings and so on.
