Abstract
The present invention relates to use of a novel, single-component additive for addition to thermoplastics, in particular polyvinyl chloride (PVC). The resultant reduced friction delays melting of the thermoplastic during extrusion and therefore improves fluidity and lowers the process pressure required. The reduced friction moreover facilitates processing in shaping machinery by reducing adhesion to metal. In order to provide these technical improvements, the present invention provides a novel poly(meth)acrylate-based additive for thermoplastics, in particular for PVC. This features a poly(meth)acrylate backbone and long alkyl solid chains.
