| titleOfInvention | Perfluorovinyloxy polyether carboxylic acid alkali metal salt and method for producing the same |
| abstract | A perfluorovinyloxy polyether carboxylic acid alkali metal salt represented by the general formula is provided:n nCF 2 ═CF[OCF 2 CF(CF 3 )] b O(CF 2 ) a O[CF(CF 3 )CF 2 O] c CF(CF 3 )COOM [I],n nwherein M is alkali metal, preferably sodium or potassium, a is an integer of 1 to 6, preferably 2, and b+c is an integer of 0 to 6, preferably 0 or 1. This perfluorovinyloxy polyether carboxylic acid alkali metal salt is produced by subjecting a perfluorovinyloxy polyether carboxylic acid alkyl ester represented by the general formula:n nCF 2 ═CF[OCF 2 CF(CF 3 )] b O(CF 2 ) a O[CF(CF 3 )CF 2 O] c CF(CF 3 )COOR [II],n nwherein R is an alkyl group having 1 to 12 carbon atoms, a is an integer of 1 to 6, and b+c is an integer of 0 to 6; to hydrolysis or solvolysis in the presence of an alkali metal hydroxide. |
