description An aqueous dispersion includes a self-crosslinking alkylolacrylamide containing interpolymer, the interpolymer being prepared in an emulsion polymerization medium by way of interpolymerizing in the medium: (a) acrylamide monomer; (b) Nâ??C2 to C10 alkylolacrylamide monomer, wherein the molar ratio of acrylamide:Nâ??C2 to C10 alkylolacrylamide interpolymerized is at least 0.5; and (c) at least one or more additional ethylenically unsaturated monomers added to the medium in an amount of from about 80 weight % to about 98 weight % based on the dry weight of monomer interpolymerized in the medium. The dispersions are particularly useful as binders for fibrous webs. Una dispersión acuosa incluye una alquilolacrilamida autoreticulante que contiene interpolímero, el interpolímero se prepara en una medio de polimerización de emulsión por medio de una interpolimericación en el medio; (a) monómero de acrilamida; (b) monómero de alquilolacrilamida NC2 a C10, en donde la relación molar de acrilamida:alquilolacrilamida N-C2 a C10 interpolimerizado es al menos 0.5; y (c) al menos uno o más monómeros adicionales no saturados etilénicamente agregados al medio en una cantidad de aproximadamente 80% en peso a aproximadamente 98% en peso con base en el peso en seco del monómero interpolimerizado en el medio; las dispersiones son particularmente útiles como aglutinantes para redes fibrosas.
