## Abstract Poly(propylene) samples produced by heterogeneous Ziegler‐Natta catalysts containing different internal electron donors were fractionated by using temperature rising elution fractionation; some key fractions were analyzed with ^13^C NMR. It was found that internal electron donors with d

Polypropylene (PP) prepared with the MgC1z/TiC1,-A1Et3/PhzSi(OMe)2 catalyst system was fractionated by a preparative temperature rising elution fractionation (TREF) technique in the wide temperature range of room temperature to 13OoC. The results of fractionation showed that there were plural active
