The kinetic model for the complex formation of NdCl 3 with isopropyl alcohol (ROH) is developed. This model will connect the initial diameter of NdCl 3 particles with the composition of NdCl 3 · n ROH complex obtained from them, the kinetics of complex formation and the molecular mass characteristics of polyisoprene which is synthesized on NdCl 3 · n ROH-Al( i -C 4 H 9 ) 3 -piperilen catalytic system. The developed model allows us to predict the composition of NdCl 3 · n ROH complex, which is optimal for the production of polyisoprene with low molecular mass, which has high flowability and it is able to act as a component of a vulcanizing sealant.
