ABSTRACT:
Chemical additives disclosed for reducing “plate-out” which have applications in polymers, such as polyolefins. It is possible to provide for a composition and a process for producing parts, sheet and film from polyolefin extrusion applications wherein the polyolefins are processed with a minimal quantity of “plate-out.” A polyolefin composition may contain a sorbitol-based clarifying system of a derivative of Dibenzylidene, along with one or more co-additives to achieve a reduction in undesirable plate-out.
