Abstract: Kinetic curves of the polymerization of 1-octene on Solvay TiCl3-AlEt3(or Al(i-Bu)3, AlEt2Cl) catalysts were determined by dilatometer, and the induction periods during which the rate increases gradually were studied.The durations of induction periods were found to decrease with increasing[TiCl3], [M]0 and with raising temperature.The breaking of the large TiCl3, particles into small particles during the induction period was observed through a microscope.Amechanistic model was suggested which ascribes the rate increasing to the breaking of catalyst particles under the effects of the formed polymer,and the model was checked with kinetic data.
