ABSTRACT

The polymerization of isoprene on titanium-magnesium nanocatalysts modified with electron-donor compounds based on organic phosphines and sulfides has been studied. It was shown that the catalyst modification makes it possible to increase the content of trans-1,4 units in polyisoprene up to 97% (according to the data of 1H NMR spectra). In the case of a catalyst modified with tributylphosphine, the effects of the phosphorus-to-titanium ratio on the polymerization kinetics, on the microstructure of trans-1,4-polyisoprene, and on the molecular mass of the polymer have been estimated.
