INFLUENCE OF THE FUNCTIONAL MONOMER/TEMPLATE RATIO IN THE PREPOLYMERIZATION MIXTURE ON THE SORPTION PROPERTIES OF MOLECULARLY IMPRINTED POLYMERS OF ORGANIC COMPOUNDS

摘要

Using acrylamide and methacrylic acid as functional monomers,polymers molecularly imprinted with 4-hydroxybenzoic acid,sodium 4-aminosalicylate,barbital,nicotinamide,and histamine as templates were synthesized.Corresponding blank polymers were prepared in the same manner,omitting the template.Conditions of polymer synthesis were optimized by means of the functional monomer/template ratio variation in the prepolymerization mixture.The values of the specific surface area of the obtained materials were estimated and their sorption properties studied.It was established that for the majority of the investigated systems,the best recognition was observed for polymers synthesized with the monomer/template ratio of 1:1.
