Abstract

A study was made of atactic PP obtained using various catalytic systems based on TiCl₃. It was shown that on replacing the cocatalyst (AlEt₂Cl for AlEt₃) in the system the constant of chain propagation changes. The atactic PP formed differs in structure and MW. It was also shown that the addition of hydrogen into the polymerization system has no effect on the MW of atactic PP obtained with the system TiCl₃ +AlEt₂Cl but regulates MW of atactic PP obtained using the TiCl₃+AlEt₃ system. Results of this study enabled a conclusion to be drawn about the formation of atactic and isotactic PP on various active centres.
