Amino and ammonium groups have been introduced into polyglycidylmethacrylate (PGMA) resins by reaction of trimethylamine either by opening the epoxide ring of PGMA or by reaction with methyl iodide followed by amination, The aminoalky derivatives were phosphorylated to afford grafted phosphotriamides; when loaded with tungsten species in their peroxo form, these polymeric carriers exhibited excellent properties as catalysts for the epoxidation of cyclohexene with hydrogen peroxide.
