ABSTRACT:
Compositions suitable for use as dry strength additives comprising water soluble polyamidoamine/epchlorohydrin resin bearing polyol sidechains wherein the weight fraction of the polyol in the resin is less than 50 percent by weight and the polyol sidechain is attached to the polyamidoamine/epichlorohydrin resin by carbon-nitrogen bond, such as amide bond or secondary or tertiary amine bonds.
