Obiettivo The crystallization and morphology of a wide range of polypropylene grades has been studied using both idealised and 'real' processes. The idealised systems include isothermal crystallization, crystallization at high cooling rates and crystallization under elongation and shear flows. The 'real processes' are a cast film process and the injection moulding of a disc. The large amount of resulting data have been used to construct a series of linked computer models that allow the prediction of morphological parameters in terms of polymer characteristics and processing conditions. The models are linked together with a final processor that allows actual product properties to be predicted.Europe has a strong position in production and use of polypromylene (PP), but competition from abroad is increasing. The industry can best meet this by increased R&D efforts with the objective to move more of the production from standard to specialty products, giving higher payback. The objective of the project is to develop a computer program to be used as a new tool for:- Development of new specialty-grades of PP with tailor-made properties. - Product and processing optimisation in injecdtion moulding and cast film.Starting from the large number of scientific studies on PP, the project will develop a model which first predicts the morphology of a small, local region in a PP-article, in terms of molecular characteristics, basic crystallization kinetics data an the thermo-mechanical history of the local region. It then predicts local mechanical properties in terms of the morphology. The model will at first be applicable to a limited range of PP grades and set of end properties that strongly depend on the crystallization behavior, but can later be extended to apply to other polymers.The model will be implemented as a computer program, and its industrial validity will be tested on two concrete industrial development challenges, in cast film and injection moulding. Positive results are expected to give an increase in sales per year which is larger than the project cost.
