  • Nonfluorinated polyurethanes and methods of making and using thereof
    Patent number: 8716396
    Abstract: Described herein are nonfluorinated polyurethanes having (a) a plurality of silicon polyol units and (b) a plurality of organic polyol units, wherein at least one of the organic polyol units has an ionizable group, and wherein the nonfluorinated polyurethanes are terminated by amino groups. The polyurethanes can be applied to a variety of different articles. The polyurethanes can impart a number of beneficial properties to an article including, but not limited to, liquid repellency, stain resistance, and bleach resistance. The nonfluorinated polyurethanes described herein are as effective or perform substantially better than fluorinated compounds currently used in the market. Methods for making the nonfluorinated polyurethanes are also described herein.
