Synthesis and thermal characterization of porous polymeric microspheres functionalized with thiol groups

Abstract The paper presents a method of the preparation and functionalization polymer microspheres consisting glycidyl methacrylate (GMA) crosslinking agents: 1,4-dimethacryloyloxybenzene (1,4DMB) trimethylolpropane trimethacrylate (TRIM). Poly(GMA- co -1,4DMB) poly(GMA- -TRIM) were obtained by seed swelling polymerization. To introduce thiol groups into structure, reaction with thiocarboxylic acids was performed. chemical structure parent modified confirmed FTIR Raman spectroscopy. Elemental composition after determined elemental analysis. analysis showed percentage sulfur in range 2.78–4.51%, which corresponds to concentration group 0.87–1.41 mmol g ?1 . Additionally, porous copolymers investigated using low-temperature nitrogen adsorption–desorption method. starting are characterized specific surface 150–160 m 2 , whereas functionalized indicate slightly lower area, about 130 thermal stability materials differential scanning calorimetry thermogravimetric course degradation under oxidative conditions is different from copolymers. much higher (approximately 270 °C) compared (230–250 °C).
