Abstract

The computational experiments were carried out on the model of butadiene polymerization (toluene as a solvent) in the presence of TiCl4–Al(i-C4H9)3 catalytic system, physically modified in turbulent flows. It was shown that, the higher is the feed rate of reaction mixture into the tubular turbulent apparatus with diffuser-confuser design, and the larger is the ratio of the diffuser diameter to confuser diameter, and the greater is the diffuser opening angle, the lower are the number-average and mass-average molar masses of polybutadiene. These values of number-average and mass-average molar masses of obtained polybutadiene under upper conditions allows using it as a polymer component of sticky glue.
