    摘要: An extrudable composition comprising thermoplastic hydrocarbon polymer, poly(oxyalkylene) polymer and fluorocarbon polymer. The poly(oxyalkylene) polymer and the fluorocarbon polymer are present in the composition in such relative proportions and concentrations as to reduce the occurence of melt defects during the extrusion of said hydrocarbon polymer composition.
