titleOfInvention | Oil, water and solvent resistant paper by treatment with fluorochemical copolymers |
abstract | A copolymer composition for treating paper and paper products to impart water, oil or grease repellency comprising monomers copolymerized in the following percentages by weight: (a) from about 60 % to about 90 % of at least one monomer of formula (I): Rf-Q-A-C(O)-C(R)=CH2, wherein Rf is a C2-20 straight or branched-chain perfluoroalkyl group, R is H or CH3, A is O, S, or N(R'), wherein R' is H or a C1-14 alkyl, Q is C1-15 alkylene, C3-15 hydroxyalkylene, -(CnH2n)(OCqH2q)m-, -SO2-NR'(CnH2n)-, or -CONR'(CnH2n)-, wherein R' is H or C1-4 alkyl, n is 1 to 15, q is 2 to 4, and m is 1 to 15; (b) from about 10 % to about 40 % of at least one monomer of formula (II): (R1)2N-CH2CH2-O-C(O)-C(R2)=CH2, wherein R1 is C1-3 alkyl, R2 is H or a C1-4 alkyl radical, and wherein the nitrogen is from about 40 % to 100 % salinized; and, (c) from about 1 % to about 7 % of at least one monomer of formula (III) or (IV): Cl-CH2-CH(OH)CH2-O-C(O)-C(R4)=CH2, or a mixture thereof, wherein R3 and R4 are each independently H or the same or different C1-4 alkyl radical is disclosed. |
