除了纯聚丁二烯橡胶外，苯乙烯-丁二烯嵌段共聚物还可用于生产粒径小于1mm的产品，这些产品具有高光泽和高刚性。但与聚丁二烯含量相近的体系相比，其韧性较低。其他橡胶系统已成功应用于工业。含苯乙烯嵌段共聚物的Hips产品粒径小，光泽好。由苯乙烯-丁二烯嵌段橡胶和/或乙丙橡胶（EPDM）组成的橡胶共混体系可与聚丁二烯共混。该产品的橡胶粒径分布具有双峰特性、高光泽和高抗冲击性。三元乙丙橡胶（EPDM）和块状橡胶不相容，形成大颗粒分散的橡胶相。由于三元乙丙橡胶（EPDM）的高度不饱和度，有必要添加更高浓度的过氧化物交联剂（二叔丁基过氧化物），以稳定橡胶颗粒并提高接枝率

另一种替代橡胶系统是径向不对称聚合物（ARPS）。ARPS有四个长度相等的聚丁二烯臂，其中一个与聚苯乙烯链相连。通过混合ARPS聚丁二烯制备的Hips产品产生两个分离的橡胶相，具有不同的形态和粒度分布。ARPS产生胶囊结构，聚丁二烯产生由多层结构包裹的正常细胞结构。该产品具有高光泽和高抗冲击性

High trans polybutadiene has relatively high heat resistance, which makes hips have advantages in processing. On the other hand, because of its regular structure, the polybutadiene crystallizes at about 0 ℃, so the low temperature toughness of polystyrene produced by this method is reduced.

In addition to pure polybutadiene rubber, styrene butadiene block copolymers can also be used to produce products with particle size less than 1 mm, which have high gloss and high rigidity. But compared with the system with similar content of polybutadiene, its toughness is lower. Other rubber systems have been successfully used in industry. Hips products with styrene block copolymer have small particle size and good gloss. The rubber blend system composed of styrene butadiene block rubber and / or ethylene propylene rubber (EPDM) can be blended with polybutadiene. The rubber particle size distribution of the product has bimodal characteristics, high gloss and high impact resistance. EPDM is not compatible with the block rubber and forms large particles as dispersed rubber phase. Due to the high degree of unsaturation of EPDM, it is necessary to add a higher concentration of peroxide crosslinking agent (di-tert-butyl peroxide) to stabilize rubber particles and improve grafting degree.

Another alternative rubber system is radial asymmetric polymer (ARPS). ARPS has four polybutadiene arms of equal length, one of which is attached with polystyrene chain. Hips products prepared by blending ARPS polybutadiene produce two separated rubber phases with different morphology and particle size distribution. ARPS produces capsule structure, while polybutadiene produces normal cellular structure coated by multilayer structure. The product has high gloss and high impact resistance.
