摘要：

It is shown that titanium-magnesium catalysts (TiCl4/MgCl2 and TiCl4/MgCl2/SiO2) in combination with triisobutylaluminum are highly effective in the polymerization of butadiene and isoprene. The rate of polymerization and the microstructure of the polymer are controlled by the Al : Ti molar ratio in the catalytic system and the reaction temperature; polymerization of butadiene proceeds with a noticeable rate even at temperatures below O degrees C. Polymerization of the studied dienes load's to the predominant formation of trans-isomers and is not accompanied by the oligomerization. According to the data of DSC and X-ray diffraction, the resulting polybutadiene is a mixture of trans-1,4-homopolymer with a small amount of the polymer of mined structure.
