Abstract: SLs-AA superabsorbent polymers were synthesized by solution copolymerization using acrylic acid and sodium ligninsulfonate. The influences of synthesis conditions on reaction and on product properties were investigated and the optimal synthesis conditions were identified. The results were: the mass contents of the crosslinking agent and initiating agent were found to be 0.315 8%-0.411 2% and 5.53%-6.27%, respectively; n(KOH)/n(AA) was found to be 40%-47%; the monomer mass content was found to be 24%-28%; the polymerization temperature was found to be 72-76℃; and the mass content of the sodium ligninsulfonate was found to be 33.54%. The copolymerization mechanism was discussed. The samples were characterized by Fourier transform infrared spectroscopy (FTIR).
Key words: functional polymer materials; sodium ligninsulfonate; acrylic acid; synthesis condition; performance; superabsorbent polymer
