Abstract:
1. A method of imparting oil repellency and grease repellency to a substrate comprising contacting the substrate, which is selected from the group consisting of cellulosic papers, paper products, flexible paper-like nonwoven products, and inorganic materials in fibrous form, with a copolymer prepared from monomers copolymerized in the following percentages by weight: (a) from about 60% to about 90% of a monomer of Formula 1, or a mixture thereof: wherein: R R is H or CH Q is —(C R each n is independently 1 to about 6, x is 0 to about 4, p is 1 to about 20, and y is 0 to about 4, provided that x+y is a positive integer; (b) from about 10% to about 25% of a monomer of Formula 2, or a mixture thereof: wherein R, is H or CH R Z is —O— or —NR wherein R r is 0 to 4, and q is 1 to 4, provided that the nitrogen bonded to R 2 and R 3 is from about 0% to 100% salinized, quaternized, or present as amine oxide; and (c) from about 1% to about 15% of a monomer of Formula 3, or a mixture thereof: wherein R is H or CH R R d is 1 to about 10, and e is 0 or 1, provided that when Formula 1 is wherein m is from about 1 to about 10, then Formula 3 is present at a minimum of about 4% by weight.
