| Abstract: | The kinetics of butadiene polymerization with tow catalyst systems consisted of Nd(naph)3 and Al (i-Bu)3 or Al(i-Bu)2H was studied and a polymerization rate equation was obtained.It was found that the molecurlar weight of polybutadiene derceased with the increase of conversion.The concentration of active center and the kinetics parmeters in the two systems were determined. |
