Temporary wet strength resin polymers having the formula [Figure] wherein A is a polar, non-nucleophilic unit which does not cause said resin polymer to become water-insoluble; B is a hydrophilic, cationic unit which inparts a positive charge to the resin polymer; each R is H, C1-C4 alkyl or halogen

Temporary wet strength resin polymers having the formula [Figure] wherein A is a polar, non-nucleophilic unit which does not cause said resin polymer to become water-insoluble; B is a hydrophilic, cationic unit which inparts a positive charge to the resin polymer; each R is H, C1-C4 alkyl or halogen; wherein the mole percent of W is from about 5% to about 95%; the mole percent of X is from about 3% to about 65%; the mole percent of Y is from about 1% to about 20%; and the mole percent of Z is from about 1% to about 10%; said resin polymer having a molecular weight of from about 5,000 to about 200,000. These resins, when incorporated into paper products provide good dry and initial wet tensile strength together with excellent wet tensile decay.
