Waterborne coatings are described having an acceptable balance of properties both during the storage of coating, application and drying. The period in which irregularities in a freshly applied coating can be repaired without resulting in brush marks is referred to as the open time. Aqueous coatings generally employ dispersed high molecular weight polymers as binders. These binders often provide short open times when the coating is dried since the dispersed polymer particles tend to be immobilized quickly in the edge region of an applied coating. As a result, the viscosity of the coating increases rapidly, which leads to a limited window of workability. The instant invention provides additives that are not volatile but that will extend the time that the film is malleable after it is applied without interfering with other attributes, such as the resistance of the coating to freezing while in the can prior to application.

Disclosed is a fluorinated polymer of the formula: RSP, wherein R is a fluorocarbyl group, S is sulfur, and P is: (i) polyglycerol; (ii) poly(allyl glycidyl ether); (iii) a copolymer of glycidol and allyl glycidyl ether, the copolymer having one or more allyl groups; or (iv) poly(allyl glycidyl ether) or copolymer of glycidol and allyl glycidyl ether, wherein one more of the allyl groups have been replaced with a functional group as described herein. Also disclosed is a method of preparing the fluorinated polymer. The fluorinated polymer finds use in improving the hydrophilicity of porous hydrophobic membranes such as PTFE and PVDF.
