Treatment of resins to lower levels of CPD-producing species and improve gelation stability |
摘要 |
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. |
