CA 2560351

A waterproofing/oilproofing agent composition which has excellent water and oil resistance. The composition comprises an aqueous medium and a fluorocopolymer comprising units of a monomer represented by (Z-Y)nX(wherein Z is C1-6 perfluoroalkyl, etc.; Y is alkylene, etc.; n is 1 or 2; and X is a polymerizable unsaturated group), units of a monomer represented by CH2=CR1-G- (R2O)q-R3 (wherein R1 is hydrogen, etc.; R2 is C2-4 alkylene; q is an integer of 1 to 50; G is -COO(CH2)r- (wherein r is an integer of 0 to 4); and R3 is hydrogen, etc.), and units of a monomer represented by CH2=CR4COO-Q-NR5R6 (wherein R4 is hydrogen, etc.; Q is C2-4 alkylene, etc.; and R5 and R6 each is C1-8 alkyl, etc.).

Composition d'agent d'hydrofugation/d'oléofugation laquelle a une excellente résistance à l'eau et à l'huile. La composition comprend un milieu aqueux et un copolymère fluoré comprenant des unités d'un monomère représenté par (Z-Y)nX (où Z est un perfluoroalkyle en C1-6, etc. ; Y est un alkylène, etc. ; n vaut 1 ou 2 ; et X est un groupe insaturé polymérisable), des unités d'un monomère représenté par CH2=CR<1>-G-(R<2>O)q-R<3> (où R<1> est un hydrogène, etc. ; R<2> est un alkylène en C2-4 ; q est un nombre entier valant 1 à 50 ; G est -COO(CH2)r- (où r est un nombre entier valant 0 à 4) ; et R<3> est un hydrogène, etc.), et des unités d'un monomère représenté par CH2=CR<4>COO-Q-NR<5>R<6> (où R<4> est un hydrogène, etc. ; Q est un alkylène en C2-4, etc. ; et R<5> et R<6> sont chacun un alkyle en C1-8, etc.).
