Mathematical Models for Polymerization Processes of Ziegler-Natta Type designing new molecules and new materials with specific properties. A strong and continuous stimulus comes from technological applications in various fields, in which the demand of better performing materials is more and more intense.

Multidimensional Theory of Crystal Nucleation theory has been applied to crystallization of polymers by Lauritzen and Hoffman [.], Mandelkern [.], Frank and Tosi [.]. The original theory concerned one-dimensional growth of molecular (atomic) clusters and could not explain more complex processes, like crystallization in oriented systems, effects of potential fields, anisotropic growth, etc.

Classical Kinetic Theory of Nucleation and Coarsening early stages of these processes, nucleii of solid phase are formed and grow by incorporating particles from the surrounding liquid phase. There is a critical value for the radius of a nucleus that depends on a chemical drive potential, which is proportional to the supersaturation for small values t

Book 2003 shaping of the catalysts. Chapter 1 (due to A. Fasano ) is devoted to a review of some results concerning the modelling of the Ziegler- Natta polymerization. The specific ex am pie is the production of polypropilene. The process is extremely complex and all studies with relevant mathematical conten

J. C. Neu,Luis L. Bonillaa patterns in the deep sea can be explained in terms of processes and ecological interactions. We applied this approach in four distinct fields of study: trophic interactions; biodiversity and ecosystem function; distribution and diversity patterns; and connectivity patterns. All four illustrate the
