Latest Patents

Wilm Stevels holds 1 patent for his invention titled "Reduced byproduct high solids polyamine-epihalohydrin compositions." This patent describes a process for rendering a polyamine-epihalohydrin resin storage stable. The process involves treating a resin composition formed in a reaction with a specific molar ratio of epihalohydrin to secondary amine group. The composition must have a solids content of at least 15 wt % and include CPD-forming species. By using at least one enzymatic agent, the process inhibits, reduces, or removes the CPD-forming species, resulting in a gelation storage stable reduced CPD-forming resin. This innovation ensures that the composition releases less than about 100 ppm dry basis of CPD when stored under specified conditions.
