Abstract 2322 16 16 18 Polyurethane/ureas including hydrophilic moieties and alkoxysilane groups of formula (I) -X-CO-NR-Y-Si-(Z)   (I) where X is O or NR; Ris H, C-Calkyl, substituted C-Calkyl, cycloalkyl, aryl or benzyl; Y is C-Clinear and branched alkylene; and Z is an organic group inert to isocyanate groups below 100° C. At least one Z group is an alkoxy group of 1 to 4 carbon atoms. The polyurethane/urea can be in an aqueous dispersion, which can be used to prepare coatings. The dispersion is prepared by
