Abstract: A thermosetting resin comprising a reacted A) first partially crosslinked glyoxalated polymer comprising a reacted (i) first polyacrylamide backbone and (ii) a first glyoxal component; and B) a second crosslinked glyoxalated polymer comprising a reacted (i) second polyacrylamide backbone and (ii) a second glyoxyal component; such that the first polyacrylamide backbone has a molecular weight that is less than the molecular weight of the second polyacrylamide backbone; and the first polyacrylamide backbone and the second polyacrylamide backbone have a weight ratio ranging from 75:25 to 95:5. Methods for making and using the resin. Fibrous substrates made with the resin.

Abstract: The present invention is directed to paper sizing emulsions, a method of making sizing emulsions, a method of sizing paper products, such as paper and board, and paper or board made using the method and the sizing emulsions of the invention. The paper sizing emulsions of the invention contains at least one sizing agent and a cationic liquid hydroxyalkylated starch that is pumpable and at least partially degraded. Typically, before dilution for mixing with the sizing material, the starch exists as a liquid in water and contains solids in an amount up to about 30 percent by weight, and has a viscosity of up to about 30,000 cps. The starch is diluted with water, before emulsifying the sizing agent to reduce the solids to an amount suitable for emulsification, and used to emulsify the sizing agent. The resulting emulsion can then be used to size paper and board.
