N , N -Dimethylacrylamide (DMAA) is a chemical compound from the group of amides . N , N -dimethylacrylamide can be polymerized very quickly. Since it adheres well to glass and metal surfaces, N , N -dimethylacrylamide is used as an adhesive. Copolymers with DMAA are more antistatic than most other polymers.

use

DMAA is used in the manufacture of contact lenses , as a copolymer to increase colorability, hygroscopicity and antistaticity, and in light-curing adhesives.
