Cationic polymerization of butadiene using a titanium tetrachloridetert-butyl chloride catalytic system

摘要

Cationic polymerization of butadiene using a titanium tetrachloridetert-butyl chloride catalytic system allows one to synthesize with high rates and yield fully soluble polybutadiene with controlled molecular characteristics. It was shown that the obtained cationic polybuta diene is characterized by predominantly 1,4-trans-structure and reduced unsaturation. The macromolecules of the cationic polybutadiene contain the initial tert-butyl and end chlorine-containing units.
