Procedure

(2') A mixture of 23 g of perfluoro(4-vinyloxybutyric acid), excess amount of SOCl2 and 0.5 ml of pyridine was refluxed until generation of gaseous HCl was discontinued and distilled in a distillation apparatus with a Vigreaux column, whereby 24 g of perfluoro(4-vinyloxybutyric acid) chloride was obtained as a fraction having a boiling point of 97.5°-100° C. (yield: 80%).
