Abstract

An extrudable composition comprising hydrocarbon polymer, organophosphite or organophosphate compound and fluorocarbon polymer. The organophosphite or organophosphate and the fluorocarbon polymer are present in the composition in such relative proportions and concentrations as to reduce the occurrence of melt defects during the extrusion of said thermoplastic hydrocarbon polymer.
