ABSTRACT:Terpolymer resins (BPhUF) were synthesized by the condensation of 2,2Ј-dihydroxybiphenyl [BPh] and urea [U] with formaldehyde [F] in the presence of an acid catalyst and using varied molar ratios of reacting monomers. Terpolymer resin compositions have been determined on the basis of their elemental analysis and the number average molecular weights of these resins were determined by conductometric titration in nonaqueous medium. Viscometric measurements in dimethyl formamide have been carried out with a view to ascertain the characteristic functions and constants. UV-VIS, IR, and NMR spectra were studied to elucidate the structure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
