高苯乙烯橡胶，呈白色固体，是一种非极性聚合物，其化学结构式为：  —（CH2—CH=CH—CH2）m—（CH—CH2）n— 
  采用乳液聚合技术，以高含量苯乙烯单体和丁二烯单体共聚而成。具有良好的机械性能和弹性。与天然橡胶、顺丁橡胶和丁苯橡胶等有良好的相容性。并兼具补强作用。本产品也可用于ABS、PS、AS等的增韧改性。在高温下本品也有一定的韧性和弹性，可以进行成型加工。也可进行硫化加工。
  本品结合苯乙烯含量为60-70%。本品无毒、无臭、可燃，杂质含量低，性能稳定。由于长链分子中的苯乙烯单体含量较高，赋予制品以更好的耐老化性能、更高的硬度和刚性、更大的机械强度和撕裂强度。其良好的机械性能、弹性和优良的相容性使本品具有广泛的用途。（国外称为高苯乙烯树脂） 
一．可与顺丁胶、天然胶及丁苯胶以任意比例共混，用于： 
  1.高强度仿革鞋底及发泡微孔鞋底； 
  2.高级自行车浅色外胎；各种胶辊；胶板； 
  3.电绝缘材料； 
二．与丁腈胶、氯丁胶共混，制造较高硬度的耐油橡胶制品，如纺织橡胶配件、耐油胶板、耐油胶辊等； 
  1.ABS、AS塑料等的增韧改性；透明PS板材的增韧改性； 
  2.其他橡胶的补强剂，用量可达25-50%；

High styrene rubber, a white solid, is a non polar polymer, its chemical structure is: (CH=CH - CH2 - M) CH2 - (CH2 - n) CH-
Emulsion polymerization technology, with high content of styrene monomer and butadiene monomer copolymerization. Has good mechanical properties and elasticity. Good compatibility with natural rubber, butadiene rubber and styrene butadiene rubber. And both have a strong role. This product can also be used for ABS, AS, PS, etc.. At high temperature, this product also has a certain toughness and elasticity, which can be formed and processed. Can also be vulcanized processing.
The content of this product is 60-70%. This product is non-toxic, no odor, combustible, low impurity content, stable performance. Because of the high content of styrene monomer in the long chain molecules, the products are endowed with better aging resistance, higher hardness and rigidity, greater mechanical strength and tear strength. Its good mechanical properties, elasticity and good compatibility make this product a wide range of uses. (known as the high styrene resin)
1. With butadiene rubber, natural rubber and styrene butadiene rubber blends used in any proportion:
1 high strength imitation leather soles and foam rubber soles;
2 senior light bicycle tire; all kinds of rubber rollers;
3 electrical insulation material;
. and NBR, chloroprene rubber blend, manufacturing high hardness of oil resistant rubber products, such as textile rubber accessories, resistant to oil and rubber, oil resistant rubber roller;
Toughening modification of 1.ABS, AS plastic, and the toughening modification of transparent PS sheet;
2 other rubber reinforcing agent, the amount of up to 25-50%;
