Abstract
The invention comprises fluorinated polymers consisting of units of formula <FORM:1070294/C3/1> where n is from 4 to 20. The polymers where n is from 4 to 8 are obtained by heating metallic salts of dibasic acids of formula HOOC(CF2)u-O-(CF)2)uCOOH where u is from 2 to 4, and polymers where n is up to 20 are obtained by heating a mixture of a metallic salt of a dibasic acid of formula HOOC(CF2)u-O-(CF2)uCOOH where u is from 2 to 4, with a metallic salt of a dibasic acid of formula HOOC(CF2)m-COOH where m is from 4 to 10. The salts are heated to above 200 DEG C. and carbon dioxide and elemental metal are eliminated. In examples, polymers are obtained by heating mercuric perfluorooxydipropionate and a mixture of mercuric perfluorooxydipropionate and mercuric perfluoroglutarate. Other acids suitable for the salts are mentioned.
