Beschreibung
N, N-dimethylacrylamide (DMAA) is an easily polymerized, nonionic monomer. The high reactivity and low initiation temperature of DMAA makes it appropriate for copolymerization. Copolymers of DMAA with N, N-dimethyl-N, and N-diallyl ammonium chloride (DMDAAC) can be used as polymeric flocculants for water treatment. The unique structure of DMAA shows amelioration in hydrogels for specific applications. DMAA, along with other hydrogels, has a three-dimensional network structure that is capable of retaining water. In addition, DMAA hydrogel can be applied to remove toxic metal ions from wastewater because of its characteristic properties such as chemical stability and high adsorption capacity. DMAA can also be used for flocculation due to its ability to augment the molecular weight of the copolymers[1].

Verwenden
N,N-Dimethylacrylamide is a useful monomer for synthetic fibers and plastics. It is also used in the synthesis of photoresponsive polymers and copolymers by grafting polysiloxane on the side chain of DMA by homopolymerization or grafting cellulose to form cellulose polymers and copolymerization of methyl methacrylate with DMA or copolymerization of DMA with styrene and butadiene.
