Abstract
AbstractComonomer reactivity ratios (from kinetic and 13C NMR data), compositional homogeneity of ethylene‐propene copolymers, and molecular structure of individual fractions of the copolymers obtained with supported Ti‐Mg catalysts of different compositions were determined. The copolymerization reactivity of these systems was found to increase upon introduction of ethyl benzoate and dibutyl phthalate to the catalyst system. It was found that both lowly stereospecific and highly stereospecific catalysts have a broad distribution of active sites with respect to copolymerization reactivity. The composition of the catalysts (titanium content and stereoregulating additives) was shown to influence the reactivity ratios of the comonomers and the microstructure of the copolymers.
