Abstract

Crystallization plays important role determining structure and morphology of a polymer subjected to processing. Due to the nature of technological processes, variation of external conditions like pressure, temperature, etc. occurs during crystallization. Understanding of nonisothermal crystallization processes is therefore crucial for designing and optimization of technological processes leading to materials and commodities possesing required properties. The present paper reports results of X-ray diffraction studies on kinetics of i- polypropylene crystallization occuring during linear cooling with various rates. Application of synchrotron as a source of radiation enables time-resolved measurements and evaluation of kinetic characteristics directly from quantities related to the developing structure of the polymer.
