摘要
通过对橡胶防老剂ＲＤ生成反应的基础研究，确定了两步法合成ＲＤ的工艺路线，优化了反应条件。改进后的产品与国外最新同类产品ＡｎｔｉｇｅｎｅＦＲ质量指标相符，在二、三、四聚体含量、软化点及外观等方面均有改善，在橡胶中的应用性能更加优越。
The process in the synthesis of antioxidant RD with two-step procedure was established and the reaction conditions were optimized on the basis of the fundamental research into the formation reaction of RD. The improved product was comparable to the latest imported correspondent Antigene FR in quality. The new product was improved in the contents of dipolymer, tripolymer and tetrapolymer,the softening point as well as the appearance. It performed better in rubber.
