The Research on Porous Structure of Super Absorbent Polymer Preparation by Inverse Suspension Method

Abstract:

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. Meanwhile, SEM showed that the structure of the copolymer was full of holes.
