Resumen:
A triacrylate crosslinking agent, 2, 2´, 2´´ - nitrilotriethyl triacrylate (NTETA), was synthesized through an original procedure from triethanolamine by a reaction with acryloyl chloride. Hydrophilic polymer supports were prepared by suspension copolymerization of 2-hydroxyethyl methacrylate (HEMA) with NTETA in an aqueous medium in the presence of cyclohexane (Cyc) as inert diluent. A new macroporous polymer, at a polymerization temperature of 85°C, was obtained. Porous properties of this copolymer were studied by swelling, mercury porosimetry and scanning electronic microscopy (SEM).
