It was found that the main reason why SBS containing oil was easy to yellow was that there is plenty of polycyclic aromatic hydrocarbon in the extender oil,PAH can easily turned quinones with yellow.Antiyellowing performance of SBS can be only developed in a little extent when antioxidants were added.The anti-yellowing performanc...

研究结果表明，充油SBS产品变黄的主要原因是油品中的稠环芳烃在光氧环境中易转化为黄色的醌，添加抗氧剂对延缓产品变黄的作用不大，通过催化加氢消除填充油中的芳烃或添加适当的光稳定剂可以提高产品的耐黄变性能。
