Diacetone acrylamide has two reactive groups: N-substituted amide and ketone, which is easy to copolymerize with other ethylene and monomers, thereby introducing a ketone carbonyl group into the polymer, by using the chemical nature of the ketone carbonyl group, the polymer can undergo crosslinking and branching reactions, used to prepare various adhesives thickening agent paper reinforcing agent cross linking agent, etc. It has been widely used in the fields of coatings, adhesives, daily chemicals, epoxy resin curing agents, photosensitive resin additives, textile additives, medical and health care.
