The Research on Porous Structure Of Super Absorbent Polymer Preparation By Inverse Suspension Method
Porous structure of the super absorbent polymer (SAP) was synthesized through inverse suspension method by adding acrylic acid (AA) and acrylic amide (AM) as monomer, N,N-Methylene-bis-acrylamide (MBA) as cross-linking agent, the mixed solution of methanol and ethanol as pore-foaming agent.The factors that influenced the bibulous performance of the super absorbent polymer were studied including the dosage of cross-linking agent, the dosage of pore-foaming agent, monomer ratio, revolving speed.The Internal structure and surface morphology of SAP was characterized by scanning electron microscopy (SEM).It indicated that when the monomer ratio was m(AM)∶m(AA)=1∶2; the weight rate of cross-linking agent and pore-foaming agent were 0.06%(compared with the quality of the monomer) and 9%, the product attained the best water absorbency of 2909 g/g in distilled water, the saline absorbency was 124.5 g/g; the water absorption rate was 10 (ml/g · s).Meanwhile, SEM showed that the structure of the copolymer was full of holes.
