Abstract
This invention describes the use of organoclays as additives to plasticizers to provide a plasticizer composition, to allow the mixing of the plasticizers with thermoplastic resins in the same process used to convert the resin formulation to finished product. The use of this invention eliminates the need for a preliminary compounding step to incorporate plasticizers into thermoplastics prior to extrusion or molding.
