Synthesis of Stereoregular Polybutadiene under Ultrasonic Treatment

摘要

One of the numerous methods for affecting the multisite nature of titanium catalysts is the change in the hydrodynamic conditions in the reaction area [1, 2], which allows the synthesis of polybutadiene with a specified microstructure and molecular-weight characteristics. A special case of hydrodynamic treatment is ultrasonic stirring of the reaction mixture. However, little data on the effect of ultrasonic stirring on the molecular characteristics (average molecular weights, molecular weight distribution (MWD) and stereoreg-ularity) of polydienes and on the kinetic inhomogene-ity of a catalytic system can be found in the literature.
