摘　　要：研究了电解质溶液pH值对无磷化乳聚丁苯橡胶聚合反应速率的影响;研究了无磷电解质加料水平对乳聚丁苯橡胶聚合反应速率、胶乳机械稳定性、聚合胶乳黏度、聚合胶乳结合苯乙烯含量的影响;同时研究了无磷聚合体系氧化还原水平对反应速度的影响,确定了聚合配方。结果表明,经过对配方的调整,无磷化丁苯橡胶聚合体系与有磷体系同样稳定。The effect of pH value of electrolyte solution on polymerization rate was investigated.The effects of different amounts of phosphate-free electrolyte on polymerization rate,mechanical stability of latex,viscosity of polymer latex,and bound styrene content of product were investigated.The effect of redox level of phosphorus-free polymerization system on polymerization rate was investigated.The results show that the phosphate-free polymerization system is as stable as that of the phosphorus system after adjustment of formula.
