| Abstract: | The polymerization of butadiene was carried out by the catalyst system of Nd(naph)_3-Al(i-Bu)_3-AlEt_2Cl. Variables affecting the polymerization, such as sequence of catalyst ageing, monomer concentration, catalyst concentration, specially, nature of solvent and reaction kinetics were studied. The results showed that the polymerization rate was found to be first order to the monomer concentration. The solvent did affect the polymerization rate and molecular weight but had little influence on the microstructure of the polymer. |
