苯乙烯丁二烯橡胶（SBR）通常是通过乳液（ESBR）和溶液（SSBR）的两种普遍的合成途径由1,3-丁二烯和苯乙烯单体合成的。乳液SBR占世界SBR市场的70％，但正逐渐被SSBR接管，因为SSBR对高性能轮胎的需求很高，该轮胎可与极性填料（如SBR-二氧化硅复合材料的二氧化硅）相容。高性能轮胎具有提高燃油效率，降低碳足迹，提高耐磨性和更好的防滑性能的优势。由于对SSBR产品的需求很高，ESBR制造商正在缓慢地将其技术转换为SSBR。另一方面，与ESBR不同，基于官能化乳液的SBR（FESBR）在生产高性能轮胎方面可与SSBR媲美。FESBR可以由类似于ESBR的基于绿色环保乳液的异质过程合成。合成路线利用各种极性试剂，例如丙烯酸酯，甲基丙烯酸缩水甘油酯，丙烯腈，乙烯基羧酸，乙烯基磺酸盐，乙烯基吡啶，富马酸，衣康酸等作为第三种共聚单体，以及苯乙烯和1,3-丁二烯。FESBR牌号与二氧化硅填料兼容，并通过氢和/或化学键与极性填料表面官能团结合。FESBR和二氧化硅之间的键合允许二氧化硅通过二氧化硅表面羟基与聚合物官能团的反应而在聚合物基质中均匀分布。FESBR-二氧化硅复合材料在改善滚动阻力，更好的模量，拉伸强度，更好的耐磨性方面将提供更好的性能。和防滑性能类似于SSBR。在本综述中，讨论了特种轮胎应用中SBR，二氧化硅作为填充剂的一般介绍，FESBR的合成路线以及高性能轮胎应用中的FESBR-二氧化硅复合材料。

Synthesis of Functionalized Styrene Butadiene Rubber and Its Applications in SBR–Silica Composites for High Performance Tire Applications

Styrene butadiene rubber (SBR) is commonly synthesized from 1,3-butadiene and styrene monomers via two ubiquitous synthetic pathways, by emulsion (ESBR) and solution (SSBR) processes. Emulsion SBR accounts for 70% of the share of the world SBR market but is slowly being taken over by SSBR, as the latter is in high demand for high-performance tires, compatible with polar fillers such as silica for SBR–silica composites. High performance tires provide the benefits of increase in fuel efficiency, low carbon footprints, and high abrasion and better skid resistance properties. ESBR manufacturers are slowly converting their technology into SSBR due to the high demand of the SSBR product. On the other hand, unlike ESBR, functionalized emulsion based SBR (FESBR) can be comparable with SSBR for making high performance tires. FESBR can be synthesized from green eco-friendly emulsion based heterogeneous process similar to ESBR. Synthetic route utilizes various polar reagents such as acrylates, glycidyl methacrylates, acrylonitrile, vinyl carboxylic acid, vinyl sulfonates, vinylic pyridine, fumaric acid, itaconic acid, etc. as third comonomer along with styrene and 1,3-butadiene. FESBR grades are compatible with silica filler and bind via hydrogen and/or chemical bonding with polar filler surface functionality. Bonding between FESBR and silica allows the uniform distribution of silica in polymer matrix via reaction of silica surface hydroxyl groups with polymer functional groups. FESBR-silica composite would give better performance properties in terms of improved rolling resistance, better modulus, tensile strength, better abrasion resistance, and skid resistance similar to SSBR. In the present review, the general introduction of SBR, silica as filler in specialty tire applications, synthetic routes of FESBR, and FESBR–silica composites for high performance tire applications were discussed.
