Abstract
An object of the present invention is to provide a compound which imparts a sufficient water repellency and a suitable oil repellency to substrates such as a fiber, a paper, a wood material, a hide, a leather, a resin, a glass, a metal, etc. The compound of the present invention is a fluoroalkylcarboxylic acid of the general formula (I), and its derivative of the general formula (II) (e.g. fluoroalkyl alcohol, fluoroalkyl carboxylic acid chloride, fluoroalkylcarboxylic acid amide and fluoroalkylamine). ##STR1##
Claims1
A fluoroalkylcarboxylic acid of the general formula:
- ##STR60## wherein R.sub.1 is a fluoroalkyl, fluoroalkenyl or aliphatic hydrocarbon group having 1 to 20 carbon atoms;
- R.sub.2 is an alkylene or alkenylene group having 1 to 11 carbon atoms;
- Rf is a fluoroalkyl or fluoroalkenyl group having 1 to 20 carbon atoms;
- p is an integer of 1 to 11;
- q+r is 0 or 1;
- and t is 0 or an integer of 1 to 8;
- provided that p is an integer of 3 to 11 when R.sub.1 is an aliphatic hydrocarbon group, R.sub.2 is an alkylene group, q+r is 0 and t is 0.
