Abstract
A continuous process wherein a mechanized and automated feeding system provides precision delivery of thermally and atmospherically conditioned components to a pelletization process including extrusion, pelletization, thermal processing, drying, and post-processing of the polymeric pellets formed. The components can be combined to form solutions, dispersions, emulsions, formulations, and the like. These components can further be reacted and thermally modified to form oligomers, pre-polymers, polymers, copolymers, and many combinations thereof.
