Abstract
Our work describes how we obtain non-ionic tensides having perfluorina ted hydrophobical chain by esterification of some perfluorocarboxylic acids with polyethyleneglycols. The optimal esterification conditions for perfluorocarboxylic acids, having 7,8 and 9 carbon atoms in their molecule, with polyethyleneglycol of a 200 and 600 g/mol molecular wei ght, respectively are described. The compounds obtained, are chemicall y characterized by the hydroxyl and ester index. Some surface properti es and the usage have been also established.
