Abstract
A continuous process wherein polymers or polymeric materials can be subjected to multiple sequential processing systems of differing temperatures and process conditions to synergistically enhance the pelletization and crystallization of those polymers and polymeric formulations, dispersions, and solutions. The multiple sequential processing systems include the processes and equipment for mixing/extrusion, pelletization, multiple transportation processes, crystallization, multiple drying processes, and optional post-processing manipulations of pellets formed. Multiple serial and/or parallel crystallization processing systems are disclosed.
