苯乙烯类热塑性弹性体部分双键氢化研究

Study on hydrogenation of partial double bond of styrene series thermoplastic elastomer

对苯乙烯类热塑性弹性体部分双键氢化进行了研究,着重考察了结构调节剂、活化还原剂、加氢(主、助)催化剂的加入量对苯乙烯类热塑性弹性体部分双键氢化的影响,同时考察了反应时间、温度及压力与部分双键氢化程度的关系。结果表明:采用适当的试验条件,可使苯乙烯类热塑性弹性体部分双键氢化率达95%以上。

This paper made a study on hydrogenation of partial double bond of styrene series thermoplastic elastomer. It emphatically observed and studied the influence of the adding amount of structural regulator, activation reductant, catalyst , cocatalyst on hydrogenation of partial double bond. It also studied the relationship between reaction time, temperature, pressure and partial double bond hydrogenation. The result shows that hydrogenation rate of partial double bond can exceed 95% on suitable conditions.
