| abstract |
Substrates which have been provided with an oil-, water- and soil-repellant treatment from the group consisting of naturally occurring and synthetic textiles and their mixtures, leather, mineral substances, thermoplastic and thermosetting polymers and paper, comprise fluorine-containing compositions which comprise two components A and B. Component A is a fluorine-containing acrylic copolymer with the following comonomers: a) (meth)acrylates containing perfluoroalkyl groups CnF2n+1-X-O-CO-CR1=CH2 (I), b) monomers from the group consisting of styrene, acrylonitrile, vinyl acetate, vinyl propionate and monomers, CH2=CR4-CO--OR5 (II), c) monomers2CH2N(R9, R10) (IVa) or in quaternized form [CH2=CR11-COO-CH2CH2N(R9R10R12)](+)Y(-)(IVb) or in N-oxidized form <IMAGE> (IVc) or of the formula CH2=CR13-COO(+)Z(-)(V) Component B is a fluorine-free poly(meth)acrylate of comonomers CH2=CHR14-COO-R15 (VI) 0 to 20% by weight of comonomer (VI) can be replaced by comonomers from the group consisting of vinyl acetate, styrene, acrylonitrile, hydroxyethyl (meth)- acrylate, hydroxypropyl (meth)acrylate, glycidyl (meth)acrylate, (meth)acrylamide, N-methylol-(meth)acrylamide and N-methoxymethylol(meth)acrylamide. The weight ratio of A to B is 1:25 to 10:1. Substituents and indices are mentioned in the description. |
