The 1, 4-cis content of Low cis BR (LBR) can be controlled by the method of production and the type of catalyst. KOSYN KBR has 35% of 1, 4-cis content. It is used as a base polymer in the production of HIPS (High Impact Polystyrene),which is the main material applied to the manufacture of cabinets for home appliances, interior goods, toys, and everyday goods, due to its excellent elasticity and 1,2-vinyl content around 14%, giving it excellent reactivity. In addition, it is used in motorcycle tires, footwears, and general mechanical products.
