溶聚丁苯橡胶国内外生产现状及发展建议

溶聚丁苯橡胶（SSBR）以丁二烯-苯乙烯为单体，有机锂化合物为引发剂，使用路易斯碱化合物作为极性调节剂，在己烷或环已烷有机溶剂中通过负离子溶液聚合反应得到的一种无规共聚物。SSBR具有良好的物理性能、加工性能及抗湿滑性能而广泛应用于轮胎等橡胶制品。本文主要介绍了国内外SSBR的生产现状，分析了SSBR生产技术工艺和发展趋势以及我国SSBR的结构状况，并结合我国的实际情况，提出了我国SSBR的发展建议。

Production situation and development proposal for solution polymerized styrene-butadiene rubber at home and abroad

The solution polymerized styrene-butadiene rubber （SSBR） was synthesized by anionic solution copolymerization of styrene and butadiene with organolithium as initiator and n-hexane or cyclohexane as solvent and Lewis base as polar modifier. SSBR was used widely in tires and other rubber products for its good physical and mechanical properties and excellent wet skidding-resistance performance. This paper described the production situation of SSBR at home and abroad, introduced the manufacturing technology and process of SSBR. Taking the actual situation of our country into consid- eration, this paper put forward the developmental proposal of SSBR in China.
