高温降解法液体天然橡胶性能和方法的研究

Study on Properties and Methods of Liquid Natural Rubber by High Temperature Degradation

研究考察国产高温降解工艺生产的液体天然橡胶分子量、分子量分布、粘度、不饱和度、以及其他物性包括密度、挥发分、灰分、玻璃化温度、闪点的检测方法,结果表明国产不同等级的液体天然橡胶性能稳定,并且可根据参数的测定指导生产。

In this article,the molecular weight,molecular weight distribution,viscosity,unsaturation and other physical properties,including density,volatile matter,ash,glass transition temperature and flash point of the liquid natural rubber produced by domestic high-temperature degradation process were investigated.The results showed that the performance of different grades of liquid natural rubber produced in China was stable,and the production could be guided by the determination of parameters.
