摘　　要：使用白炭黑增强SSBR已经成为制备绿色轮胎的一种趋势,然而由于极性差别大,白炭黑在SSBR中存在团聚现象。针对这一问题,通过硫醇-烯点击化学将1-硫代甘油接枝到SSBR链中。GPC和^(1)H-NMR结果证明在LPO的引发作用下,两者成功发生加成反应。实验结果表明反应温度、反应气氛、硫醇加入量等均会对接枝率产生影响。SSBR链中接枝羟基官能团后,分子间相互作用力增强,玻璃化温度升高。The use of white carbon black to enhance SSBR has become a trend in the preparation of green tires.However,due to significant polarity differences,white carbon black is unevenly dispersed in SSBR.In response to this issue,this article uses thiol ene click chemistry to graft 1-thioglycerol onto SSBR chains.The GPC and ^(1)H-NMR results demonstrate that under the initiation of LPO,the two successfully undergo an addition reaction.The experimental results show that reaction temperature,reaction atmosphere,and the amount of thiol added can all affect the grafting rate and the conversion rate of thiol.After grafting hydroxyl functional groups into the SSBR chain,the intermolecular interactions are enhanced,and the glass transition temperature increases.
