โœฆ Synopsis

In the present communication the effect of p-toluenesulfonic acid catalyst on thermal polymerization of shellac has been investigated. The difference in activation energy for uncatalyzed and catalyzed reaction, has been computed to be 7.4 kcal. when c = 0.1%.

The activation energy for uncatalyzed reaction, calculated on this basis comes to 12.5 kcal.

The kinetics of propylene polymerization initiated by ansa-metallocene diamide compound rac-(EBI)Hf(NMe 2 ) 2 (EBI ฯญ C 2 H 4 -(indenyl) 2 , rac-1) were investigated. The rac-1 compound could be directly utilized for catalyst formations without converting to a dihalide or dialkyl complex in the prese
