Attenuated total reflectance Fourier transform infrared spectrometry has been employed to assess the degree of chlorination of hydantoin moieties which are covalently linked to the surface of the polyamide, Nylon 66. The N-chlorinated hydantoin functional groups are active in producing biocidal activity against pathogenic microorganisms upon direct contact with the surface molecules of the fabric...
We have prepared a series of monomers with the general formula diphenylamine-R-diphenylamine. The electro-oxidation of these monomers in a series of non-aqueous solvents leads to para C-C coupling of the terminal phenyl rings to produce (R-diphenyl benzidine) n , an alternating main chain unit material. Polymeric material is formed from high-polarity solvents while low-polarity solvents produce...
