Abstract: The polymerization of styrene was initiated by calixarene neodymium/di-n-butylmagnesium/hexamethylphosphoramide catalyst system. The average viscosity molecular weight of polystyrene increases as the concentration of di n butylmagnesium or the Mg/Al molar ratio in the di-n-butylmagnesium increases. This result was explained by the state of association of butylmagnesium. As the state of association of di-n-butylmagnesium increases, the average viscosity molecular weight of polystyrene increases.

Key words: Calixarene-neodymium complex, State of association of di-n-butylmagnesium, Styrene, Polymerization
