AQUEOUS DISPERSIONS OF FLUORINATED POLYURETHANES. Abstract. Fluorinated polyurethanes having a high fluorine content and a high molecular weight have been prepared by polymerization in aqueous dispersion employing large quan- tities of perfluoro-polyether diol, inserting monomers having ionizable hydrophilic functional groups into the molecule and performing the dilution in H2O with an organic diamine. The obtained fluorinated polyurethanes are employed in emulsion or as bulk dried products in low temperature applications, and for treating buildings and stone and fibrous materials. (VA-437-03/ES))
