Abstract
Procedure for obtaining fluorocarbonate eteres from formula (I), where and is an acid group or acid derivative; a, b and n are equal or greater than 0; c vale 0 or 1; x '' is chlorine or bromine; and r <037> and r '' <037> can be several types of radicals. It consists in the reaction of a compound of formula (II) with a composite of formula (III), in which all symbols have the same meaning as in formula (I). The reaction is carried out in a liquid condition, in the presence of a metal or ammonium fluoride as a stabilizer, at a temperature between -20ºc and 50ºc. These compounds have applications as intermediate for the obtaining of polymers that are used for the use of resins or membranes of ionic exchange.
