Abstract:
1. A composition comprising a wet-strength enhancing amount of (a) a functional promoter comprising a water-soluble anionic polymer having a molecular weight ranging from at least about 50,000 daltons to about 500,000 daltons and a molecular weight charge index value of at least about 10,000, and (b) polyamide strength resin component; wherein when functional promoter is used in conjunction with the polyamide strength resin component in a pulp slurry during a papermaking process, the resulting composition imparts improved wet strength to a paper product made by the papermaking process as compared to when the polyamide strength resin component is used in conjunction with a water-soluble anionic polymer that does not have a molecular weight that is at least about 50,000 daltons and a molecular weight charge index value that is at least about 10,000.
