PURPOSE: To obtain a gel for filtration having excellent acid resistance, alkali resistance, hydrophylic property, and mechanical strength, as well as separating performance for proteins by copolymerizing vinylpyrrolidone with a three-functional cross-linking agent having a triazine-ring.
CONSTITUTION: 100pts.wt. vinylpyrrolidone and 0.5W100pts.wt. compound having a three-functional triazine-ring of the formulas I and II (where R1, R2, and R3 are, respectively, -CH2-CH=CH2, -CH2-C≡CH, etc.) are copolymerized in the presence of a diluent solvent, e.g., water, metanol, etc., to obtain the gel for filtration having excellent separation performance for proteins, and hydrophylic property as well as acid resistance, alkali resistance, and mechanical strength.
