2-(tert-Butylamino)ethyl methacrylate Usage And Synthesis

Uses

Researchers reported the preparation of latex particles from 2-(tert-butylamino)ethyl methacrylate (TBAEMA) using aqueous emulsion polymerization. The preparation of PTBAEMA-functionalized polyolefin fibers via ATRP and an azide-functional initiator has been reported. Poly[2-(tert-butylamino)ethyl methacrylate](PTBAEMA) is a neutral polymer, which is inherently biocidal with potential application in antifouling paints and coatings. The major role of PTBAEMA is to displace Ca2+ and/or Mg2+ ions from the outer membrane of the bacteria, which is accordingly disorganized and finally disrupted. This pendent bulky secondary amine does not need quaternization for antibacterial properties[1-2].

Safety Profile

Poison by intraperitoneal route. See also ESTERS and AMINES. Combustible when exposed to heat or flame. To fight fire, use alcohol foam, water spray or mist, dry chemical. When heated to decomposition it emits toxic fumes of NOx.
