ABSTRACT:
There is disclosed a low temperature blending process for preparing formulations comprising a polyvinyl chloride resin intimately admixed with a polyacrylate-modified PVC process aid, these formulations being particularly suited for use in various forming processes such as extrusion, calendering and injection molding which result in the manufacture of shaped articles such as pipes, rods, sheets and films whose surfaces are characterized by their high degree of smoothness and glossiness.
