Synthesis, characterization and antimicrobial activity of ResorcinolMelamine-Formaldehyde resin

A copolymer was synthesized from resorcinol and melamine using formaldehyde as a cross linking agent at 126 0C in 2M HCl medium. The resin was characterized by elemental analysis, FTIR and NMR spectra. The RMF resin was tested for its inhibitory action against pathogenic bacteria and fungi. The resin show potent inhibitory action against bacteria such as Escherichia coli, Klebseilla, Staphylococcus aureus and Pseudomonas aeruginosa and fungi viz. Aspergillus flavus, Aspergillus niger, Pencillium species, Candida albicans, Cryptococcus neoformans and Mucor species. The copolymer resin is soluble in DMF, DMSO, THF, conc. H2SO4.

Intrinsic Viscosity

Intrinsic Viscosity is defined as the nonzero viscosity intercept extrapolated to zero concentration of solute, which is measure of the solute/solvent interaction. The Intrinsic Viscosityis generally designed by the symbol ?. Since this quantity is taken to represent a minimum as the concentration of solute approaches zero, it is assumed that the configuration of the solute is in relaxed condition and occupies a preferred, or optimal solvent accommodation. An expression known as the Mark-Howink relation can be used to determine values related to the shape and size of the particles giving rise to theIntrinsic Viscosity.
