Most of polymerization reactions with Ziegler catalysts operate through the 'non-living' mechanism, whereas lanthanide catalysts show a living-mechanism character. The degree of 'livingness' in a polymerization reaction is generally investigated through kinetics and the product analysis rather than
## Abstract Poly(propylene) samples produced by heterogeneous ZieglerβNatta 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
