Molecular imprinted polymers (MIP) were prepared by the copolymerization of styrene (S) or methyl methacrylate (MMA) and methacrylic acid (MAA) using ethylene glycol dimethacrylate (EGDMA) as the crosslinker with molar ratios of [monomer]/[crosslinker] and [MAA]/[template] of 3:7 (to obtain a rigid structure) and 1:6 (to optimise hydrogen interactions), respectively. The polymerizations occurred in presence of the template molecule (MIP)-GlcNcouma-an amphiphilic monosaccharide. The same materials, non-imprinted polymers (NIP), were also prepared in absence of the template. These MIPs were characterized and used as SPE supports for selective enrichment. The results showed the correlation between retention efficiency and the porogen character of the polymerization solvent. (C) 2007 Elsevier B.V. All rights reserved.
