    摘要： A process for rendering a polyamine-epihalohydrin resin storable stable, comprising: treating a composition containing a polyamine-epihalohydrin resin which includes CPD-forming species with at least one acidic agent, wherein the pH during treatment is about 1.1 or less; the time is for at least about 2 hours to at least about 24 hours, and the temperature is at least about 30 °C to at least about 90 °C, wherein the temperature range is combined with the time period range in an inverse relationship, to at least one of inhibit, reduce and remove the CPD-forming species to obtain a gelation storage stable reduced CPD-forming resin so that the composition containing the reduced CPD-forming polyamine-epihalohydrin resin, when stored at pH 1 for 24 hours at 50 °C and measured at 24 hours, produces less than about 500 ppm dry basis of CPD.
