摘要： This invention is directed to method for improving the dry strength of a paper product using a single cationic dispersion polymer strength additive, wherein the cationic dispersion polymer is prepared by polymerizing in an aqueous solution of a polyvalent anionic salt in the presence of a dispersant: i. a cationic diallyl-N,N-disubstituted ammonium halide monomer of formula (H2C═CHCH2)2N+R1R2X−  wherein R1 and R2 are independently C1-C20 alkyl, aryl or arylalkyl and X is an anionic counterion and ii. an acrylamide monomer of formula  wherein R3and R4 are independently hydrogen, C1-C10 alkyl, aryl or arylalkyl; R5 is hydrogen or methyl and R6 and R7 are independently hydrogen or C1-C10 alkyl.
