摘　　要：对丁苯橡胶进行了改性,通过考察聚合反应转化率、相对分子质量调节剂的用量、结合苯乙烯含量、残余单体含量、聚合反应时间等参数对改性丁苯橡胶门尼黏度的影响,探讨了改性丁苯橡胶门尼黏度的影响因素。结果表明,在影响官能化丁苯橡胶门尼黏度的众多因素中,相对分子质量调节剂用量对门尼黏度影响最大,残留单体含量影响也很大。The styrene butadiene rubber was modified.Influence factors of Mooney viscosity of modified SBR were studied.The effects of amount of residual monomer,amount of molecular weight regulator,polymerization conversion rate,and bound styrene content on Mooney viscosity of modified SBR were investigated.The results show that the amount of molecular weight regulator has the greatest impact on Mooney viscosity of modified SBR,and the amount of residual monomer has also great effect.
