Diacetone acrylamide (DAAM) is a new type of functional monomer, which occupies an important position in the chemical industry. This article reviews the preparation technology of DAAM and its application progress in coatings and other fields in recent years. Diacetone acrylamide can be prepared by using diacetone alcohol and acrylonitrile, acrylamide and diacetone alcohol, acrylamide and isopropenyl acetone as raw materials, and strong acid or heteropolyacid as catalyst. Due to the unique configuration of the multifunctional group, the DAAM molecule is very active in chemical properties, has many excellent properties, and can perform various reactions, such as polymerization reactions, cross-linking reactions, addition reactions, etc. , moisture retention, water absorption and other characteristics, in the fields of coatings, daily chemical products, photosensitive resin additives, adhesives, epoxy resin curing agents, gelatin substitutes, medical materials, polyester resin crosslinking agents and paper strengthening agents The application is becoming more and more extensive.
