Resumen:
New copolymers of ethylene glycol dimethacrylate/2-hydroxyethyl methacrylate [poly(EGDMA-co-HEMA)],2,20,200-nitrilotriethyl
triacrylate/2-hydroxyethyl methacrylate [poly(NTETA-co-HEMA)] and pentaerythritol tetraacrylate/2-hydroxyethyl methacrylate [poly-
(PETA-co-HEMA)] were obtained by suspension polymerization at 70 or 85 8C, using cyclohexane (Cyc) as porogen. In this work, the
influence of the crosslinking agent (di, tri, or tetravinyl monomer) on the morphology of the polymeric networks was investigated. Swelling
studies, Fourier Transform Infrared (FTIR) and mercury intrusion porosimetry, demonstrated that when both the vinyl groups number and
molecular chain length between double bonds of the crosslinking agent decreased, networks with high porosity and crosslinking degree were
generated.co-HEMA)],2,20,200-nitrilotriethyl
