Abstract
In this paper we present a kinetic approach to the analysis of transient-state homogenous Ziegler-Natta polymerization activity data. The main features of the experimental data are discussed and fitted to transient kinetic models.
Highlights
Despite the fact that Ziegler-Natta homogeneous polymerization has been extensively studied, the lack of a systematic kinetic approach is clear, in particular concerning transient data
In this paper we present a kinetic approach to the analysis of transient-state homogeneous Ziegler-Natta polymerization activity data
The possibility that the reaction needs more than one monomer molecule coordinated to proceed opens up a whole range of possible steady-state kinetic rate laws, and involves some new possibilities in relation to transient state kinetic data
Summary
Despite the fact that Ziegler-Natta homogeneous polymerization has been extensively studied, the lack of a systematic kinetic approach is clear, in particular concerning transient data. This type of data, carrying a lot of information, is usually less tractable and requires the derivation of more complex models. In this paper we wish to present a preliminary systematic study on the kinetics of the transient-state process. The main features of the experimental data reported in [1,2,3,4,5] are dealt with by the model, in particular the order of the reaction in relation to the monomer and the existence of induction periods and deactivation.
