Synthesis of a Novel SAP with PS Foam
A super-absorbent polymer (SAP) is synthesized with polystyrene foam (PSF) and sodium acrylate through inverse emulsion polymerization. The influence of experiment conditions such as solvent of PS, composition of comonomers, initiator and cross-linking agent on the absorption capacity of the resins are discussed. The maximum water absorption rate of the prepared SAP is about 1600g/g.
