Abstract:
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) N—C2 to C10 alkylolacrylamide monomer, wherein the molar ratio of acrylamide:N—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.
