Abstract

High cis-1,4 liquid polybutadiene (cLBR) and polyisoprene (cLIR) with narrow molecular weight distribution were prepared by the chain-transfer coordination polymerization. The effects of cLBR and cLIR on the physical and dynamic mechanical properties of carbon-black filled composites containing single polybutadiene (PBR) or a blend of PBR/polyisoprene (PIR), were investigated. The results showed that cLBR and cLIR effectively ameliorated filler dispersion compared with the treated distillate aromatic extract (TDAE) oil. The wet skid resistance and rolling resistance of vulcanized PBR/PIR composites plasticized with 5 phr cis-1,4 liquid rubbers were significantly improved. Therefore, a new type of plasticizers cLBR and cLIR that are environmental benign and highly compatible with matrix rubbers, has been discovered to replace the conventional TDAE oil used in fabricating the “green” tyres.

高顺式-1,4-液态聚二烯对碳-黑填充复合材料性能的影响

通过链转移配位聚合法制备了分子量分布较窄的高顺式-1,4液态聚丁二烯（cLBR）和聚异戊二烯（cLIR）。研究了 cLBR 和 cLIR 对含有单一聚丁二烯（PBR）或 PBR/ 聚异戊二烯（PIR）混合物的碳-黑填充复合材料的物理和动态机械性能的影响。结果表明，与经过处理的蒸馏芳烃萃取（TDAE）油相比，cLBR 和 cLIR 能有效改善填料的分散性。用 5 phr 顺式-1,4 液体橡胶增塑的硫化 PBR/PIR 复合材料的湿滑阻力和滚动阻力得到了显著改善。因此，我们发现了一种新型增塑剂 cLBR 和 cLIR，这种增塑剂对环境无害，与基体橡胶高度兼容，可以取代传统的 TDAE 油，用于制造 "绿色 "轮胎。
