N2 - Data on the content of fractions with different microtacticities for polypropylene (PP) samples produced over three catalysts [the "donor-free" titanium-magnesium catalyst and catalysts with dibutyl phthalate and 1,3-diether(fluorene) used as internal donors] upon polymerization in the absence/presence of an external donor (ED) have been obtained by preparative temperature rising elution fractionation method. The effect of internal and EDs on the distribution of PP fractions with different microtacticity is discussed.

Correlations were found between microtacticity, molecular weight, and the melting points of these fractions.
