Development and characterisation of molecularly imprinted suspension polymers

TL;DRAbstract

A controlled photo-polymerisation procedure for the synthesis of spherical molecularly imprinted polymer (MIP) beads through the use of a suspension polymerisation methodology is described.\nAs molecular imprinting moves towards commercialisation, the need to produce packing materials with good flow properties is critical.\nA comparative study of non-covalent MIPs synthesised by suspension and bulk polymerisation methods using 2-aminopyridine (2-apy) as a template and methacrylic acid (MAA) as functional monomer to produce acrylate polymers is reported. The influence of experimental parameters such as temperature, agitation speed and cross-linker i.e. trimethylolpropane trimethacrylate\n(TRIM) and ethylene glycol dimethacrylate (EGDMA) was examined in order to assess their impact on binding performance, yield, morphology and particle size distribution in the different polymers. It was concluded that for improved polymer performance, longer polymerisation times and lower temperatures re
