| titleOfInvention | Membrane separation process for removing residuals from polyamine-epihalohydrin resins |
| abstract | This invention relates to a process for preparing polyamine-epihalohydrin resins having reduced levels of residuals. The process comprises (a) charging a membrane separation apparatus with an aqueous composition comprising at least one polyamine-epihalohydrin resin, and (b) separating the aqueous composition into a permeate and a retentate by passing the aqueous composition through the membrane of the membrane separation apparatus. The retentate comprises at least one polyamine-epihalohydrin resin having lower levels of residuals on an equal active component basis than the aqueous composition of (a). The permeate comprises residuals removed from the aqueous composition of (a) and less than 5% by weight of the active component of said at least one polyamine-epihalohydrin resin. The polyamine-epihalohydrin resins having reduced levels of residuals can be used to make wet strength agents, dry strength agents, creping adhesives for paper products, curing agents for wood product adhesives, and other products. |
