摘　　要：采用烯烃复分解法将生物基腰果酚(CA)接枝到1,2-聚丁二烯橡胶(1,2-PB)上制备了苯酚官能化的液体1,2-PB(1,2-PB-g-CA)。结果表明,CA成功接枝到聚丁二烯上,并且在开放体系下可得到官能度大于10%的接枝产物。将1,2-PB-g-CA作为白炭黑填充的丁苯胶轮胎胎面胶配方体系的增塑剂可提高白炭黑在基体中的分散性。同时,此改性低聚物羟基的存在有利于增加白炭黑和橡胶基体的相互作用。且该硫化胶具有较低的滚动阻力和生热性能。With the increasing development of green and sustainable chemistry,bio-based additives in rubber materials become a hotspot.However,compared with traditional additives,bio-based additives had lower relative molecular weight and higher polarity,which led to poor processing property and mechanical properties.Cardanol(CA),a by-product of the cashew industry,is a renewable and inexpensive organic natural resource that can be easily obtained via the vacuum distillation of roasted cashew nut shell liquid(CNSL).Researchers grafted CA onto liquid isoprene rubber through a free radical mechanism,but the reported methods were usually complicated and the grafted rubber was prone to gel.In this study.
