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.
