Abstract:
1. A polymeric composition consisting of (i) a first polymeric stage, wherein said first polymeric stage consists of a first polymeric component and, optionally, one or more additional polymeric components, wherein said first polymeric component consists of a polymer consisting of units derived from one or more monomers selected from the group consisting of butadiene and C (ii) a second polymeric stage applied over said first polymeric stage, wherein said second polymeric stage has a Tg of at least 30° C., wherein said second polymeric stage comprises at least 50 weight percent of units derived from methyl methacrylate or styrene, and (iii) optionally, a third polymeric stage that is an intermediate layer between said first polymeric stage and said second polymeric stage, wherein said third polymeric stage comprises units derived from C wherein said polymeric composition reduces the time required for solid polyvinyl chloride resin to form a homogeneous melt upon exposure to heat and mechanical work, and wherein said polymeric composition lubricates polyvinyl chloride resin.
