Products Description of Diacetoneacrylamide CAS#2873-97-4

Diacetone acrylamide has two reactive groups: N-substituted amide and ketone. It is very easy to copolymerize with other ethylene and monomers, thereby introducing ketocarbonyl groups into polymers. By utilizing the chemical properties of ketocarbonyl groups, polymers can undergo crosslinking and grafting reactions, and are used to prepare various adhesives, thickeners, paper reinforcing agents, crosslinking agents, etc. It has been widely used in coatings, adhesives, daily chemicals, epoxy resin curing agents, photosensitive resin additives, textile additives, medical and health fields.

Product Application of Diacetoneacrylamide CAS#2873-97-4

An important vinyl monomer. The homopolymer generated by polymerization is insoluble in water, but has "water breathing properties". The water absorption rate can reach 20-25% of the resin's own weight. When the ambient humidity is lower than 60%, the water absorbed by the polymer is released again. The water acts as a plasticizer for the polymer. This unique property can be used for a variety of purposes.

(1) Hair perm resin with good moisture resistance Japan uses it for hair perm resin with moisture resistance. The hairstyle can be kept for a long time and will not deform in rain or washing.

(2) Photosensitive resin This product is used as part of the raw material of photosensitive resin, which can have the following characteristics:

Fast photosensitivity; After exposure, the non-image part can be easily removed to obtain a clear image; It can obtain a layout with good strength, solvent resistance and water resistance. In addition, it can also be used as a crosslinking agent for unsaturated polyester resins, a crosslinking agent for diallyl phthalate, and a curing agent for epoxy resins, such as "water-breathing" resins (contact glasses, anti-fogging glass, ship bottom coatings, etc.), pressure-sensitive adhesives, adhesive modifiers, non-woven fabric adhesives, water-absorbent films, leather finishing agents and modifiers, paper strength enhancers, antistatic polymers, inks, etc.
