Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 35 (Septembre 2012) . - pp. 11401-11408 Titre : Synthesis of cross - linked, partially neutralized poly (Acrylic Acid) by suspension polymerization in supercritical carbon dioxide Type de document : texte imprimé Auteurs : Yazan A. Hussain, Auteur ; Tao Liu, Auteur ; George W. Roberts, Auteur Année de publication : 2012 Article en page(s) : pp. 11401-11408 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Supercritical state Carbon dioxide Suspension polymerization Résumé : A novel process for producing superabsorbent polymer of cross-linked, partially neutralized poly(acrylic acid) via suspension polymerization in supercritical carbon dioxide was developed. The process utilized siloxane-based surfactants as suspension stabilizers to produce particles with acceptable size range for commercial applications. The behavior of the suspension mixture and its relation to the final product morphology is discussed. The product performance in terms of water absorbency is presented.
