Abstract
The kinetic inhomogeneity of polysite titanium- and neodymium-based catalysts for the industrial production of cis-1,4-polyisoprene significant studied. The titanium- and neodymium-based catalysts are characterized by the presence of two and three types of active sites, respectively. Modification, including hydrodynamic treatment, of the titanium and neodymium catalyst makes it possible to prepare monosite systems with the same kinetic activity.
