ABSTRACT:
Hydroscopic polymer gels can be formed by applying a polymer to a surface and allowing water to be sequestered from the atmosphere into the polymer. The polymer gels are formed using methods and compositions employing water soluble or water dispersible copolymers having: (i) a first monomer that is acidic and is capable of forming an anionic charge in the composition; (ii) a second monomer that is amphipathic; (iii) optionally, a third monomer that is hydrophobic; and (iv) optionally, a fourth monomer that that has a permanent cationic charge or that is capable of forming a cationic charge on protonation. The polymer gels are particularly substantive and effective at modifying surfaces such as glass and hydrophobic polymeric substrates to provide soap scum and soil resistance, and easier next time cleaning benefits.
