Abstract:
A composition comprised of(a) a polymeric cationic wet strength agent, (b) a synthetic polymeric cationic dry strength agent different from said (a), having from about 1 to about 15% of cationic recurring units, by mole based on total moles of recurring units, wherein said synthetic polymeric cationic dry strength agent increases the wet strength of paper by about 15% or less, and (c) water, wherein the weight ratio of said (a) to said (b) is in the range of about 1:4 to 4:1, and wherein a sample of said composition, prepared by mixing (a) and (b) in water to provide a 15% solids composition, by weight based on total weight, remains pourable for at least about 25 days after preparation when stored at about 35Â° C.
