摘要: The kinetic features of polymerization with an active site comprising cobalt dihalides (CoX2, where X = Cl, Br, I) activated by methylaluminoxane (MAO)|were investigated in 1,3-butadiene polymerization. catalytic system exhibited the characteristic living initiation (ki)|and propagation (kp)|rate coefficients were estimated using model for slow previously reported Shionoet al.1 energy activation reaction was calculated to be 27–30 kJmol−1. marked changes rate observed different halides could adequately described terms variations process, same Arrhenius curve fitting from all three halides, suggesting that halide does not participate growing chain end.
