Procedure

Hexafluoroisobutylene (HFIB)/Vinyl Alcohol (VOH) Copolymer. Fifty grams of the poly(HFIB/VOAc) prepared above, 500 ml of methyl alcohol, and 25 ml of 25 wt % sodium methoxide in methyl alcohol were refluxed for 6 hours. Over this period additional methyl alcohol was added as ˜860 ml of methyl alcohol were distilled off. Addition of resulting polymer solution to water gave a gummy precipitate. The water was decanted off and the precipitate taken back into 200 ml of methyl alcohol and reprecipitated with 500 ml of water in a Waring blender. Vacuum filtration, drying under pump vacuum and then for 24 hours in a 75° C. vacuum oven gave 37 g of poly(HFIB/VOH) as off white granules.
