Latest Patents

Vinciguerra holds a patent for a "Membrane separation process for removing residuals from polyamine-epihalohydrin resins." This invention relates to a process for preparing polyamine-epihalohydrin resins with reduced levels of residuals. The process involves charging a membrane separation apparatus with an aqueous composition containing at least one polyamine-epihalohydrin resin. The aqueous composition is then separated into a permeate and a retentate by passing it through the membrane. The resulting retentate contains polyamine-epihalohydrin resin with lower levels of residuals, while the permeate consists of the removed residuals and less than 5% by weight of the active component of the resin. These resins can be utilized in various applications, including wet strength agents, dry strength agents, creping adhesives for paper products, and curing agents for wood product adhesives.
