The Theoretical Study of Kinetics of NdCl 3 · nROH Catalytic Complex Formation for the Process of Obtaining a Low-Molecular Polyisoprene as the Component of Vulcanizing Sealant

摘要

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.
