Relationship of Molecular-Mass Characteristics of Polyisoprene, Component of Vulcanized Sealant, with Particle Sizes of Catalytic System TiCl4–Al(i-C4H9)3 in Isoprene Polymerization

A model of isoprene polymerization kinetics in the presence of the catalytic system TiCl 4 –Al( i -C 4 H 9 ) 3 has been developed. The feature of the model is its ability to forecast molecular-mass characteristics of polyisoprene on the basis of particle sizes of the catalytic system. It allows one...

Summary:A model of isoprene polymerization kinetics in the presence of the catalytic system TiCl 4 –Al( i -C 4 H 9 ) 3 has been developed. The feature of the model is its ability to forecast molecular-mass characteristics of polyisoprene on the basis of particle sizes of the catalytic system. It allows one to select such sizes which provide necessary fluidity for the use of polyisoprene as a component of vulcanized sealant.
