摘　　要：采用中国石油吉林石化公司乳聚丁苯橡胶高转化率大生产配方,考察了实验室聚合反应釜聚合反应单体转化率随反应时间的变化,测定了生胶的结合苯乙烯含量、有机酸和皂含量、门尼粘度等性质,结果表明:反应10 h,转化率为70%左右时生胶的各项性质均达到标准GB/T 8655—2006中规定的优等品指标要求;当反应12 h,转化率达到75%时,生胶的结合苯乙烯含量和门尼粘度不符合要求。The monomer conversion of styrene butadiene rubber（SBR） polymerization was studied by a lab scale autocalve with the large-scale production recipe of high conversion for SBR in Jilin Petrochemical Company.And then the intermediates properties such as the combining styrene content,organic acids and soap content,Mooney viscosity in emulsion polymerization were all determined.The results showed that the performances of synthesized product with the polymerization time of 10 hours and monomer conversion up to 70% can meet up with the superior grade requirements of GB/T 8655-2006,while the combining styrene content and Mooney viscosity of synthesized product with the polymerization time of 12 hours and monomer conversion of 75% can not meet up with the superior grade requirements of GB/T 8655-2006.
