FLUORINATED URETHANE COMPOUNDS AND COMPOSITIONS CONTAINING THE SAME

摘要

A fluorine-containing urethane compound of the general formula: ÄRf-A<1>-(X<1>(OH))-(Y<1>)a-OC(=O)NH-Üm IÄ-NHC(=O)O-Y<2>ÜnÄ-NHC(=O)O- ((ClCH2-)X<2>O)b-R<1>Ük wherein I is a group remaining after an isocyanate group is removed from a polyisocyanate compound, Rf is a perfluoroalkyl group having 2 to 21 carbon atoms, A<1> is a direct bond or a divalent organic group having 1 to 21 carbon atoms, X<1> and X<2> are trivalent linear or branched aliphatic group having 2 to 5 carbon atoms, Y<1> is a divalent organic group having 0 to 5 carbon atoms and 0 to 2 nitrogen atoms (provided that at least one carbon atom or nitrogen atom is present) and at least one hydrogen atom, Y<2> is a monovalent organic group optionally having a hydroxyl group, and R<1> is a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, can impart high water- and oil-repellency.
