Abstract:
1. A method of providing oil repellency, water repellency, and dynamic water repellency to a substrate comprising contacting the substrate with a polymer composition comprising A) a first polymer comprising, on a water free basis, wherein a is 1 to from about 10; R is hydrogen, C said first polymer in contact with B) a second polymer comprising, on a water free basis, wherein R wherein R is hydrogen, C provided that the first polymer comprises from about 20% to about 75% by weight of the polymer composition; wherein the hydrophobized nanoparticles is dispersed within the first polymer (A); wherein the nanoparticles are a surface modified inorganic oxide particle comprising an oxide of M atoms independently selected from the group consisting of Si, Ti, Zn, Zr, Mn, Al, and combinations thereof; and wherein at least one inorganic oxide particle has a surface covalently bonded to at least one group represented by formula (IV) wherein: L R
