| Abstract: | Kinetics on the polymerization of butadiene with (BF_3OEt_2 +n—C_8H_(17)OH)(called as Ni—Al—B)system as catalyst has been studied, The result shows that the rate is around zero order reaction on Ni] and is around negative first order reaction on Al]. It is suggested that the rate equation of the polymerization is - dBd]/dt = k'Ni]~0Al]~(-1)B]~0Bd] Al/B≤1 - dBd]/dt =k'Ni]Al]~(-1)B]Bd] Al/B>1 The apparent activation energy for the polymerization is 49.2 KJ.mol~(-1). |
