A POLYMER COMPOSITION CONTAINING AN EXTRUSION PROCESSING AID COMPRISING A FLUOROCARBON ELASTOMER AND VINYLIDENE FLUORIDE

摘要

High molecular weight hydrocarbons which are susceptible to melt processing difficulties such as decomposition or rough surface are efficiently extruded by employing a fluorocarbon elastomer and a crystalline vinylidene fluoride polymer as a processing aid. The aid enables the extrusion rate to be increased while maintaining the melt stability and a good extrudate surface quality.
