  • Process for the production of SAP
    Patent number: 7398606
    Abstract: A continuous process for the production of dried superabsorbent polymers (SAPs) the polymerization reaction is carried out either in an initially homogenous aqueous monomer solution (bulk aqueous solution polymerization) or in a heterogeneous water-in-oil reactant mixture (reverse phase suspension or emulsion polymerization) within a continuous closed polymerization reactor, then the resulting polymer gel is dried within a continuous moved bed in a closed dryer, avoiding the needs of standard intermediate maturity tank(s).
    Type: Grant
    Filed: September 4, 2002
    Date of Patent: July 15, 2008
    Assignee: List AG
    Inventors: Sahbi Belkhiria, Pierre Alain Fleury, Ibrahim Al-Alim
