Abstract Carboxylic cation-exchange resins having both acrylic and methacrylic acid units and enhanced content of cross-linking agent triethyleneglycol dimethacrylate have been synthesized. Relative sorption values of Methyl violet and pea protein have been shown. Highly cross-linked cation-exchange resins having 20 and 24 % of cross-linker was shown to have the same relative sorption ability towards protein as the resin with 14% of triethyleneglycol dimethacrylate, but smaller specific swelling. . Pea pulp has been used for preparative protein sorption. Desorption of protein takes place at pH 6.5-7.5 what provides for protein native form preservation.
