摘要：
The possibility of using a turbulent prereactor of diffuser-confuser design for directional synthesis of butadiene and isoprene polymers and copolymers on a multisite titanium catalyst was examined. Preliminary forming of the reaction mixture under turbulent conditions decreases the contribution of low- and high-molecularmass modes with smoothing of nonmonotonic dependences of the intermediate-molecular-mass modes on the monomer ratio, which is due to disintegration of catalyst particles.
