      Divinyl benzene (DVB), ethyleneglycoldimethacrylate (EGDMA) and NN′-methylenebis-acrylamide (NN′-MBA) cross-linked poly(methyl methacrylate)(PMMA)-supported pyrazolinium chromate, chlorochromate and pyrazole-CrO3 complex resins, were prepared and used as oxidising reagents for alcohols. These resins selectively oxidise primary alcohols to aldehydes and secondary alcohols to ketones. They possess the desired characteristics of polymeric reagents, including operational simplicity, filterability and regenerability. NN′-MBA crosslinked poly(methyl methacrylate)-supported pyrazolinium Cr(VI) reagents are more efficient in terms of functional group capacity, reaction time and product yield.
