of the amorphous fluoropolymers by spraying spin coating dip coating or other film forming techniques an advantage of the hydrofluorocarbon fluid compositions taught herein is their environmental friendliness glass vials were loaded with poly hfp tfe and solvent rolling the vials for gt 24 hours room temperature caused polymer swelling rather than solution while partial solution may have occurred with some of these mixtures in these comparative examples none of the potential solvents listed gave an attractive solution with any of the amorphous perfluoropolymers tested glass vials were loaded with 0 1 g polymer and 1 ml of l h perfluorohexane the vials were rolled at room temperature if solution was not achieved after 1 to 2 days of rolling additional solvent was added as recorded in the table below glass vials were loaded with 0 1 g polymer and 1 ml of 1 h perfluorooctane the vials were rolled at room temperature if solution was not achieved after 1 to 2 days of rolling additional solvent was added as recorded in the table below glass vials were loaded with 0 1 g polymer and 1 ml of 5 6 dihydroperfluoro 5 decene the vials were rolled at room temperature if solution was not achieved after 1 to 2 days of rolling additional solvent was added as recorded in the table below glass vials were loaded with 0 2 g polymer and 2 ml of dihydroperfluoroheptane c 7 f 14 h 2 the vials were rolled for seven days at room temperature with the results recorded in the table below it has proven somewhat difficult to quantify the amount of polymer in solution when gel is present because the gel plugs filters and does not cleanly separate with centrifugation in one case described here the gel ended up as.
