Versuchsvorschrift

To 100 g of a copolymer made by the process of the present invention and having the composition 55.8 wt % vinyl acetate, 32.8 wt % TFE and 11.4 wt % HFP, was added 500 ml of methanol and 40 ml of concentrated ammonium hydroxide to form a copolymer suspension in the methanol. After three days at room temperature with occasional shaking, the resulting solution was heated to remove the reaction by-products to give a 25.1 wt % solution of polymer of composition 2.7 wt % vinyl acetate, 37.4 wt % vinyl alcohol, 44.5 wt % TFE, and 15.4 wt % HFP.
