Procedure

To the 30 wt % 1,1,2,2,3,3,4-heptafluorocyclopentane solution of a perfluoropolyetherurethane acrylate composition, 0.06 g of butylhydroxytoluene was added, followed by dissolution while stirring. The resultant solution was warmed to 50° C. and 1,1,2,2,3,3,4-heptafluorocyclopentane was distilled off under reduced pressure (under about 100 mmHg for about 1.5 hours). 460 g of 2,2,3,3-tetrafluoropropanol was added and then distilled off under reduced pressure (under about 70 mmHg for about 2 hours) to obtain a 20 wt % 2,2,3,3-tetrafluoropropanol solution of a perfluoropolyetheracrylate composition (“20 wt % fluorine alcohol solution B of a perfluoropolyetherurethane acrylate composition”).
