WT5BZ]CT catalyst is a new type titanium containing catalyst invented by Beijing Research Institute of Chemical Industry.It has high activity for ethylene polymerization.In this paper,the kinetics behavior of ethylene homopolymerization without hydrogen regulation in slurry system was studied under normal pressure with CT catalyst;the specific number of active centers[C ]and the propagation rate constants(k p)were determined by kinetic method.The high number of active centers and high propagation rate constants together account for the high activity of the catalyst system.
