Polyfunctional polymer sorbents

The gas chromatographic properties of polyfunctional polymer sorbents, particularly those based on triethylene glycol methacrylate and butyl methacrylate and N-vinyl-3(5)-methylpyrazole and ethylene glycol dimethacrylate copoymers have been studied. The thermodynamic characteristics of sorption on these polymer sorbents have been investigated. The correlation betweenchanges in the sorption energy and entropy has been determined. It has been shown that in the system sorbate—polymer sorbent, the mechanism of interaction depends on the chemical nature, physical state and structural characteristics of the sorbent and chemical nature and molecular size of the sorbate.
