POROUS STRUCTURED WATERBORNE POLYURETHANE DISPERSIONS WITH NATURAL SUBSTANCE, AND THEIR PROCESS

摘要

PURPOSE: porous water-dispersible polyurethane resin offer ensures multi-functional and hypotoxicity, can show porous structure by polymerization technique using natural material in human body. ;CONSTITUTION: porous water-dispersible polyurethane resin is obtained by synthesis of natural nano particle/water water-dispersible polyurethane resin that one-step or two-step reaction mechanism is polyurethane. There is polyalcohol (compound of reactive hydrogen :-OH ,-COOH ,-NH2) two or more OH bases to make epoxides and compound and active hydrogen by being added. The porous water-dispersible polyurethane resin of partial size is 50nm-1000& mu; m. ;The 2011 of copyright KIPO submissions
