Abstract: Two series of polymeric beads from methyl methacrylate or methyl-acrylate and divinylbenzehe were synthesized. The physico-chemical and gas chromatographic properties of these ester-containing polymers have been determined and the polarities have been evaluated by means of McReynolds polarity scale. The use of these beads for the separation of various mixtures was; well documented through several examples. It was shown.that they were better than Porapak Tand some other commercial, ayailable polymers with close polarity for the shorter retention time, lower column temperature, and higher selectivity.
