| use | important vinyl monomer. The homopolymer produced by polymerization is insoluble in water, but has "water respiration". The water absorption rate can reach 20-25% of the resin's own weight, and when the ambient humidity is lower than 60%, the water absorbed by the polymer is released again, and the water plays a role of plasticizer for the polymer. Taking advantage of this peculiar nature, many uses can be developed. (1) Perm resin with good moisture resistance Japan uses it for perm resin with moisture resistance. The hairstyle is kept for a long time without deformation due to rain and washing. (2) The photosensitive resin is used as a part of the photosensitive resin raw material, which can have the following characteristics: fast photosensitive speed; After exposure, the non-image part can be easily removed and clear images can be obtained; The layout with good strength, solvent resistance and water resistance can be obtained. 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, prevent glass Fogging, boat bottom coating, etc.), pressure-sensitive adhesives, adhesive improvers, non-woven fabric adhesives, water-absorbing films, leather finishing agents and modifiers, paper strength enhancers, anti-static polymers, inks, etc. Mainly used as a homopolymer, widely used in coatings, perm resins with good moisture resistance, spray styling agents, photosensitive resins and their additives, etc. |
| production method | is obtained by reacting acrylonitrile and acetone in concentrated sulfuric acid. |
