Chemical Properties
liquid
Uses
4-Aminostyrene undergoes graft copolymerization with poly(tetrafluoroethylene) (PTFE)1 and Si surface,2 followed by oxidative copolymerization with aniline. Thus, it renders PTFE and Si surface conductive.1 4-VAn is coupled with hydrogen terminated Si surfaces for electroless metal and synthetic metal deposition.3 Palladium(II) schiff base complexes derived from Allylamine and vinylaniline has been reported.4 It also acts as a second surfactant for coating nanomagnetic particles.5 It is used in functionalization of single-walled carbon nanotube through solvent free functionalization.
Definition
ChEBI: 4-Vinylaniline is a member of styrenes.
