Preparation of hybrid hydrogel based on pregelatinized starch modified with poly (AA-NaAA- AM-AMPS) latex

Hybrid hydrogels based on pregelatinized starch was synthesized through modification of pregelatinized starch with poly (AA-NaAA-AM-AMPS) latex. After modification of pregelatinized starch the hybrid hydrogels were surface treated to improve absorbency under load. Surface crosslinking was carried out using of hybrid hydrogel andethyleneglycoldiglycidylethere (EGDG E) as a crosslinker. Swelling capacity of modified pregelatinized starch was 38.53g/g in distilled water and 23.61g/g in 0.9% NaCl solution. AUL of modified pregelatinized starch before and after surface treatment was 7g/g and 13.16g/g respectively
