    Abstract: Processes for rendering a polyamine-epihalohydrin resin storage stable, including processes that prepare a storage stable resin and/or processes that treat resins. A composition containing a polyamine-epihalohydrin resin with a solids content of at least 15 wt% treated with at least one enzymatic agent under conditions to at least one of inhibit, reduce and remove the CPD-forming species. A paper product containing the storage stable polyamine-epihalohydrin resin, when corrected for adding at about a 1 wt% addition level of the resin, contains less than about 250 ppb of CPD.

    Abstract: A process for treating a composition containing a polyamine-epihalohydrin resin that has a low level of CPD-producing species and good gelation stability is disclosed. A polyamine-epihalohydrin resin is prepared with a ratio of epihalohydrin: amine of less than about 1.1:1.0; The resin is then subjected to a base treatment followed by an acid treatment resulting in a resin that has good gelation storage stability and produces low levels of CPD.
