PREPARATION, CHARACTERIZATION AND APPLICATION OF POLY(HYDROXYETHYL METHACRYLATE -co- ACRYLAMIDE) AS NON IONIC WATER-SOLUBLE POLYCHELATOGEN

The free radical copolymerization of soluble poly(hydroxyethyl methacrylate-co-acrylamide) was studied in the range 25 to 75 % in the feed. The copolymers compositions were determined from the N/C by elemental analysis. The r1 and r2 were determined by the Kelen Tüdös method. The experimental data i...
