Abstract

The research of the ESR and ENDOR for isoprene polymerization catalysts has been carried out.It is concluded that catalytically active centres in these catalysts are alkaline octahedron complexes Ti3+ with the trigonal distortion. The obtained dependencies between the ESR spectra parameter variation and the component proportions, the temperature and the catalyst preparation time are used in the synthetic rubber industry for the ESR control in the technological process of isoprene polymerization catalyst preparation.
