tailor made of polypropylene through designing package of internal/external donor in ziegler natta catalysts

An insight into the effect of diether and succinate structures on both internal and external donor roles on the performance of mgcl2/id/ticl4 is developed. catalyst s performance mainly including activity, hydrogen response and molecular weight distribution is explained through the coordination nature of external donors and its correlation with the internal donor. this report offers the unique opportunity of studying the behavior of diether and succinate on both internal and external donor roles and guides us in designing catalyst system according to the characteristics of desired polypropylene.
