A few new thiodicarboxylic acids and thiodiols were obtained by condensation reaction of 4,4'-bis(mercaptomethyl)benzophenone (BMMB) with some halogen acids or halogen alcohols, respectively, in aqueous sodium hydroxide solution.



By melt polycondensation of one of these acids, i.e. benzophenone-4,4'-bis(methylthioacetic acid) (BBMTAA) with 1,5-pentanediol, a new linear polyester was obtained, and by melt polyaddition of one of these diols, i.e. benzophenone 4,4'-bis(methylthiohexanol) (BBMTH) with hexamethylene diisocyanate (HDI) a new linear polyurethane was obtained.



The structures of monomers and polymers were confirmed by elemental analysis and FT-IR and H-1 NMR spectroscopy. The polymers were studied to describe their physicochemical, thermal and mechanical properties.
