Fabio N. P. de Freitas,Esther DweckSome models describing the Ziegler-Natta polymerization are reviewed, and their mathematical aspects are discussed. A model for the heterogeneous polymerization is developed assuming a continuous approximation of the catalyst site distribution. Some mathematical results about these models are presented.

Isobaric Crystallization of Polypropyleneansitions from liquid to solid state. Starting from the experimental data on isobaric crystallization of polypropylene provided by Montell (Ferrara, Italy), we illustrate a mathematical model based mainly on the papers [.], [.], and [.] that leads to a correct physical description of the process.

https://doi.org/10.1057/9781137314048ie. It is shown that corresponding results can be obtained from both models. Application of the model to a piston-driven extrusion flow shows the occurrence of spurt oscillations for a restricted range of prescribèd inlet flow rates. The found oscillations are qualitatively in correspondence with ex
