| dc.description.abstract | Superabsorbent polymer fibres with maximum water absorbency were produced using acrylonitrile and methyl methacrylate as monomers, N-hydroxymethyl acrylamide as potential cross linking agent, dimethyl sulfoxide as solution and azo-bisisobutyronitrile as initiator. The copolymer solution was then spun using dry-wet spinning method with water as coagulation bath. The fibres thus produced were heated to get crosslinking structure and their surfaces were hydrolyzed by alkaline solution. The influence of hydrolyzing conditions, such as temperature and concentrations of alkaline solution and N-hydroxymethyl acrylamide,on the fibre structure and properties was also studied using FTIR, DSC, DMA and SEM techniques. The changes in storage modulus, Tg and surface structures of fibres were also studied. The superabsorbent polymer of about 40g/g water absorbency was obtained using N-hydroxymethyl acrylamide concentration of equal to about 10wt%monomer, alkali concentration of about 15wt% and hydrolyzing time of about 5 min. | en_US |
