HYDROGELS FROM ACRYLIC ACID WITH N,N-DIMETHYLACRYLAMIDE: SYNTHESIS, CHARACTERIZATION, AND WATER ABSORPTION PROPERTIES

Copolymer hydrogels of acrylic acid (AA) with N,N-dimethylacrylamide (NNDMAAm) were synthesized by solution free radical polymerization at different feed mol monomer ratios. The monomer reactivity ratios were determined by Kelen-Tüdös method. According to that, the monomer reactivity ratios for poly...
