実験手順: Using essentially the procedure as in Example 1, a mixture of perfluorobutyric acid fluorides (3.77 g with acyl fluoride content of 81%, 14 mmol), KF (1.02 g ,17 mmol), the ethoxyisobutene (4.56 g with purity 88%, 0.18 mmol) in 8.33 g diglyme was agitated at room temperature for four days. The reactor was vented to yield 0.67 g liquid which comprised (GC %): 88% starting acyl fluorides mixture and 8% C4F9OC2H5. The reaction solution remaining in the reactor was vacuum distilled to yield 3.0 g of a mixture which comprised (GC %): 75% C4F9OC2H5, 1.5% C2H5C(CF3)2C(O)F and 7.6% starting vinyl ether. After decarboxylation by treatment with triethylamine, the remaining diglyme solution yielded 1.45 g CF3CH2CF3 (purity 98% contaminated with 1.5% C4F9OC2H5 and 0.5% (CF3)CC2H5C(O)F). Triethylamine recovery gave 2.5 g organic liquid material with b.p. up to 101° C., consisting of (GC %): 2.5% CF3CH2CF3, 42% triethylamine, 9% starting vinyl ether and 29% diglyme. Calculated yields were: C4F9OC2H5, 72% on the consumed acid fluoride mixture, CF3CH2CF3, 75% on consumed vinyl ether.

実験手順: The cyclic carboxylic anhydride can be used in an amount of about 10-70, preferably about 35-70 mol percent. More preferably 45-60 mol percent of ethylenically unsaturated cyclic anhydride is copolymerized with 40-55 mol percent of at least one C2 to C30 aliphatic 1-alkene to produce a copolymer such as, e.g., a maleic anhydride/octadecene copolymer, maleic anhydride/decene copolymer, and maleic anhydride/tetradecene copolymer. It is also contemplated to copolymerize 45-60 mol percent of a cyclic carboxylic anhydride with 40-50 mol percent of a vinylether of preferably less than 30 carbon atoms to produce a copolymer such as, e.g. a maleic anhydride/octadecyl vinylether copolymer or maleic anhydride/methylvinylether copolymer. It is further contemplated to copolymerize 45-60 mole percent of a cyclic carboxylic anhydride with 40-55 mol percent styrene to produce, e.g. a maleic anhydride/styrene copolymer. to produce a copolymer such as, e.g.
