Abstract
Colloidal microgel particles may be prepared by an emulsion polymerisation technique. It is often advantageous to prepare microgels from two or more monomers to confer different physico-chemical properties. The distribution of one monomer relative to another within a microgel structure may be determined by neutron scattering. Data will be presented for the distribution of butyl acrylate and N-isopropylacrylamide in a co-polymer microgel prepared from the two monomers. Further for a co-polymer of N-isopropylacrylamide and vinyl pyridine, Raman spectroscopy has been used to determine the concentration of vinyl pyridine in the microgel particles. The concentration of a given monomer in a microgel is often different to the starting concentration in the reaction mixture due to different reactivity ratios. Data will be shown that co-polymer microgels offer potential for drug delivery and the distribution and ratio of the two monomers can have a profound effect on their capacity to deliver drug molecules.
