我国官能化溶聚丁苯橡胶的研究进展及生产现状

Research Progress and Production Status of Functionalized Solution Polymerized Styrene Butadiene Rubber in China

总结溶聚丁苯橡胶(SSBR)的官能化改性技术、官能团种类及改性橡胶性能等研究进展。介绍了我国官能化SSBR生产现状,2024—2025年我国将新增18万t·a^(-1)官能化SSBR产能。建议国内SSBR企业改进合成工艺路线,研究价廉且易得的原料,开发新型官能化及高效引发体系,增加产品品种和牌号,建设可柔性切换生产品种的装置,避免无序竞争。

The research progress on the functionalization modification technology,functional group types of solution polymerized styrene butadiene rubber(SSBR)and the properties of modified rubber are summarized in this paper,and the current production status of functionalized SSBR in China is introduced.China will add 180000 tons per year production capacity of functionalized SSBR in 2024—2025.It is recommended that domestic SSBR enterprises improve the synthesis process routes,develop inexpensive and easily available raw materials,develop new functionalization and efficient triggering systems,increase product varieties and grades,and build equipment capable of flexible production switching.
