摘要：
A storage stable polyaminopolyamide-epihalohydrin resin, said resin, when stored as an aqueous composition containing the resin, and when stored at pH 1 for 24 hours at 50 °C and measured at 24 hours, produces less than about 1000 ppm dry basis of CPD; said resin being produced from a reaction of a) polyaminoamide prepolymer having an acid functionality of less than about 0.5 milliequivalents/dry gram of prepolymer and b) epihalohydrin, said prepolymer being end-capped prior to reaction with epihalohydrin by reaction with an endcapping agent.
