Popis: Experiments were performed in an attempt to explain the probable mechanism present in the polymeric grafting process and to determine the percentual ratio between N-4-[4-(dietylamine) fenil] fenilmetilene-2–5-cyclohexadiene-1-ilidene-N-etil ammonium monomer and the sulfate (1 : 1) (Green Vinyl Malachite: GVM) in poly-N-vinylcarbazole/Green Vinyl Malachite, PNVC/GVM, specimens of the copolymerization product. Computerized spectroscopic techniques, optimized for maximum absorption and minimum effect noise, were utilized to subtract the spectral information of the GVM monomer noncopolymerized species from the macromolecular base with no special sampling techniques. The samples were processed using the standard PECDS software with the infrared Data Station. The copolymerization process resulted in a 52.91% concentration of a noncopolymerized fraction consisting of dimerized structures of the reactant monomer.
