<p>Disclosed is a composition for processing aid which is improved in properties for preventing sticking between fluorine rubbers. Specifically disclosed is a composition for processing aid which is composed of a fluorine rubber. This composition for processing aid is characterized in that the fluorine rubber has a ratio of the weight average molecular weight [Mw] to the number average molecular weight [Mn], namely [Mw]/[Mn] of 1.3-3.0.</p>
