摘要：

A simple model is proposed to examine the possible effect of chlorine mobility in titanium chlorides on the dynamics of polymerization rate. The range of value of Cl- diffusivity is estimated to be 10(-17) to 10(-15) cm(2)/s. The model was verified by simulation of experimental data were found in the literature. (c) 2004 Elsevier B.V.
