Polymer Crystallization under Process Conditions

Part of the NATO ASI Series book series (NSSE, volume 302)


First, a description is given of the principles of a correct treatment of the solidification of a crystallizable body in a cooling process. As a second step, a simplified but still realistic model for primary nucleation is presented. According to this model the number of nuclei as a function of crystallization temperature is specified for i-PP and HDPE, both polymers, as rather quickly crystallizing polymers, being of industrial interest, in contrast to slowly crystallizing model polymers. Accessible paths for the determination of spherulitic growth speeds are discussed. Results are given for the above mentioned polymers. The description of the influence of flow on the crystallization kinetics of polymers is reserved for a second paper.
