N,n-dimethyl Acrylamide (Dmaa)

We are making, exporting and supplying of N,N-Dimethyl Acrylamide (Dmaa) in Jinan, Shandong, China. DMAA/NNDMA is easily polymerized by the free radical process using BPO and AIBN ,etc.,as initiators.And co-polymerized readily with styrene,methyl methacrylate,acrylonitrile methacrylate and various other monomers.

Excelling in compatibility, DMAA dissolves in all solvents except n-hexane.

As DMAA readily copolymerizes with other vinyl monomers, different copolymers that vary in DMAA content can be obtained.

DMAA homopolymers exhibit high hygroscopic and anti-static properties although it is non-ionic substances.

In the presence of a persulfate, crosslinking reaction between DMAA and acrylamide proceeds in a aqueous solution of a DMAA- acrylamide copolymer due to dehydrogenation of N-substituted methyl groups.
