PREPARATION METHOD OF FLUOROPOLYMER PROCESSING AID
A preparation method of a fluoropolymer processing aid. The preparation method comprises the following steps: simultaneously adding ε-caprolactone and a fluoropolymer elastomer into a reactor, and heating to completely dissolve the fluoropolymer elastomer; and then cooling, adding polyol, mixing thoroughly, and adding an organotin catalyst to carry out a polymerization reaction; and after the reaction is finished, carrying out cooling, pulverizing or spray granulation so as to obtain the fluoropolymer processing aid. The processing aid prepared by using the method can reduce the extrusion pressure of a polymer during extrusion, improve the processing efficiency, improve the phenomena of melt rupture and “sharkskin” during polymer extrusion, and effectively enhance the surface quality of a product. Compared with the prior art, the processing aid of the invention has the characteristics of uniform dispersed particle size during polymer processing, no coking at a die head during long-time polymer extrusion processing, etc.
