Abstract

Un proceso para preparar dispersiones acuosas de polímeros, que comprende la polimerizacion de monomeros vinilo de adicion, constituidos por un primermonomero de formula (1) para formar una dispersion acuosa que comprende un primer polímero cationicoexpandible en agua o soluble en agua, donde R1 es H o CH3,A es O o NH; B es un grupo alquileno o alquileno ramificado u oxialquileno que tiene de 1 a 5 carbonos, R2 es un grupo metilo, etilo o propilo, R3 es un grupometilo, etilo o propilo, R4 es ungrupo metilo, etilo o propilo y X es un contraion; donde dicha polimerizacion se realiza en presencia de una composicionacuosa que comprende al menos un segundo polímero cationico soluble en agua, diferente de dicho primer polímero; donde, si dichosmonomeros vinilo de adicioncomprenden, además, un segundo monomero de formula (1) en donde R1 es H o CH3, A es O o NH, B es un grupo alquileno o alquileno ramificado u oxialquileno quetiene de 1 a 5 carbonos, X es un contraion; y R2, R3 o R4 se selecciona a partir del grupo formado por alquilo C4-10, bencilo y C2H4C6H5, entonces la cantidadde dicho primer monomero es mayor que la cantidad de dicho segundo monomero en base molar, y donde, si dichos R2, R3 y R4 en dicho primer monomero en conjuntocontienen un total de 3 átomos de carbono, entonces dicho primer polímero está libre de unidades recurrentes hidrofobicas. Además, se dan a conocer unadispersion obtenible por dicho proceso y un método para utilizar dicha dispersion.A process for preparing aqueous polymer dispersions, which comprises the polymerization of vinyl addition monomers, constituted by a first monomer of formula (1) to form an aqueous dispersion comprising a first water-soluble or water-soluble cationic polymer, where R1 is H or CH3, A is O or NH; B is an alkylene or branched alkylene or oxyalkylene group having from 1 to 5 carbons, R2 is a methyl, ethyl or propyl group, R3 is a grupomethyl, ethyl or propyl group, R4 is a methyl, ethyl or propyl group and X is a counterion ; wherein said polymerization is carried out in the presence of a compositional composition comprising at least one second water soluble cationic polymer, different from said first polymer; where, if said additional vinyl monomers comprise, in addition, a second monomer of formula (1) wherein R1 is H or CH3, A is O or NH, B is an alkylene or branched alkylene or oxyalkylene group having 1 to 5 carbons, X it is a counterion; and R2, R3 or R4 is selected from the group consisting of C4-10 alkyl, benzyl and C2H4C6H5, then the amount of said first monomer is greater than the amount of said second molar-based monomer, and where, if said R2, R3 and R4 in said first monomer together contain a total of 3 carbon atoms, then said first polymer is free of recurring hydrophobic units. In addition, an dispersion obtainable by said process and a method for using said dispersion are disclosed.
