✦ Synopsis

The use of macroporous copolymers of 2-hydroxyethyl mcthacrylate and ethylene dimethacrylate as sorbents for gas chromatography was investigated. It was found by determination of ROHRSCWNEIDER'S constants that the materials under investigation differed in their polarities and were particularly suitable for the fractionation of polar compounds and branched hydrocarbons. Some other characteristics of these copolymers, such as specific surface area, thermal stability and analyzing effect, were also determined and compared with the corresponding properties of styrenedivinylbenzene sorbents.
