Abstract
The invention provides a processing aid enabling short-time disappearance of melt fracture occurred in extrusion-molding a melt-fabricable resin at a high shear rate, a great reduction in extrusion pressure, and production of molded articles with good appearance. The processing aid contains a polymer containing a fluorine-containing elastomeric polymer segment and a fluorine-containing non-elastomeric polymer segment.
