Resumen:
Polymeric macroporous rod systemswere prepared using N-acryloyl-tris(hydroxymethyl)aminomethane
(NAT) and glycidyl methacrylate (GMA) as mono-vinyl monomers and N,N-methylenebisacrylamide
(BIS) or trimethylolpropane trimethacrylate (TRIM) as crosslinking agents. The reactions were performed
in the presence of a ternary porogenic diluent (composed by dimethylsulfoxide, tetradecanol
and poly(ethylenglycol) 6000 (PEG 6000)) and azobisisobutyronitrile (AIBN) as initiator, by freeradical
crosslinking copolymerization. The effect of polymerization temperature, porogenic mixture and
crosslinker was analyzed. The results showed that a lower polymerization temperature and an increase
in the amount of non-solvating diluents (tetradecanol and PEG 6000) in the reaction mixture led to products
with higher porosity. The prepared monolithswere promising as potential base supports for different
chromatography processes, especially those synthesized with GMA, since its incorporation allows to bind
different ligands in a direct coupling reaction.
