| Abstract: | A super absorbent polymer(SAP)based on sodium polyacrylate resin with large size andb eaded was synthesized by one-step inverse-suspension polymerization.The influences of different factorss uch as crosslinker agent,mix round speed,oil-to-water ratio,dispersant,initiator content and ratiow ere studied on the size and water absorption of SPA.The research results showed that maximal size andw ater absorption for the SAP were more than 2 mm and 100 times respectively.The synthesis technicsa nd post treatment p... |
