The reactions of sodium hydroxymethanesulfinate (sodium formaldehyde sulfoxylate, SFS) with various monomers, including acrylates, methacrylates, styrene and vinyl acetate, were studied. The reaction products formed depended on the molecular structure of the monomers and acidity of the reaction solution. Among the monomers studied, acrylates with resonance stability values Q between 0,38 and 0,45 produced diacrylate sulfones in neutral conditions. The other monomers or reaction conditions did not result in a dimer. The obtained diacrylate sulfones were characterized by elemental analysis, mass spectrometry, IR spectra, normal 1H and 13C NMR, CHn (n = 1, 2 and 3) subspectra by Distortionless Enchancement by Polarization Transfer at θ = 3π/4, as well as by 1H‐ 13C 2D‐NMR spectra using Correlated Spectroscopy and Heteronuclear Multiple Bonding Correlation methods. A possible reaction mechanism for the formation of dimers is suggested. The morphology and thermal properties of these diacrylate sulfones were determined.
