The comonomer distributions of commercial linear low density polyethylenes (LLDPE) and linear very low density polyethylenes (VLDPE) produced with traditional high activity Ziegler-Natta (Z-N) catalysts were characterized by temperature rising elution fractionation (TREF). In order to develop faster
## Abstract The intermolecular structural heterogeneity of a propyleneβethylene random copolymer was studied by preparative temperature rising elution fractionation combined with GPC, ^13^CβNMR, differential scanning calorimetry, and wideβangle Xβray diffraction analysis of the obtained fractions.
