Synthesis and swelling behaviour of bentonite based superabsorbent polymer composite
Bentonite based superabsorbent polymer composite(SPCwas synthesized by solution polymerization of acrylic acid and acrylamide comonomer with bentonite using ammonium persulfate(APS)as an initiator and N, N-methylenebisacrylamide(MBA)as a crosslinker.Amount of bentonite,initiator and crosslinker were...

| Summary: | Bentonite based superabsorbent polymer composite(SPCwas synthesized by solution polymerization of acrylic acid and acrylamide comonomer with bentonite using ammonium persulfate(APS)as an initiator and N, N-methylenebisacrylamide(MBA)as a crosslinker.Amount of bentonite,initiator and crosslinker were varied to get the optimum value to produce maximum water absorbency.The water absorbency determination was done by using tea-bag method The SPC were characterized by using Fourier Transform Infrared Spectroscopy(FTIR)and Thermogravimetric Analysis (TGA).The water absorbency under optimal synthesis of the SPC with Bentonite content of 10%, APS content of 0.9% and MBA content of 0.0%,it reaches more than 537 g H2O/g in distilled water respectively. |
