✦ Synopsis
An integrated view is presented of several possible mechanisms applicable to the interpretation of homogeneous ZieglerÈNatta polymerisation. In this paper, the transient aspects related to the kinetics of ZieglerÈNatta polymerisation are investigated. Extensive data are used to construct kinetic proÐles vs. (r M t) from a theoretical approach. Special attention is given to the duration of the transient period as a function of the di †erent kinetic parameters. The kinetic models developed are Ðtted to experimental data, either directly obtained by the authors or published in the literature. These general models have a broad range of application.
