Claims33
A method for producing a superabsorbent foam, the method comprising the steps of:
- forming a reaction mixture comprising at least one compound capable of forming a superabsorbent foam;
- stirring said reaction mixture;
- and
- applying mechanical waves selected from ultrasonic waves and sonic waves to said reaction mixture to form said superabsorbent foam.
A porous superabsorbent foam substantially comprised of a polymer, wherein said polymer is formed by applying sonic waves or ultrasonic waves to a stirred reaction mixture during a polymerization reaction adapted for forming said polymer.
A porous superabsorbent foam substantially comprised of a cross-linked polymer, wherein said cross-linked polymer is formed by applying sonic waves or ultrasonic waves to a stirred reaction mixture including a polymer capable of being cross-linked, said applying is performed during a cross-linking reaction adapted for forming said cross-linked polymer.
A porous superabsorbent foam substantially comprised of a polymer, said polymer is formed by applying sonic waves or ultrasonic waves to a stirred reaction mixture during a polymerization reaction adapted for forming said polymer, said reaction mixture comprises at least one monomer capable of being polymerized.
A porous superabsorbent foam substantially comprised of a cross-linked polymer, said cross-linked polymer is formed by applying sonic waves or ultrasonic waves to a reaction mixture comprising at least one monomer capable of being polymerized and cross-linked, said applying is performed during a polymerization and cross-linking reaction adapted for forming said cross-linked polymer.
A method for producing a superabsorbent foam, the method comprising the steps of:
- forming a reaction mixture comprising at least one compound capable of forming a superabsorbent foam;
- stirring said reaction mixture;
- and
- applying non-linear mechanical waves to said reaction mixture to form said superabsorbent foam.
A method for producing a superabsorbent foam, the method comprises applying to a stirred reaction mixture mechanical waves selected from the group consisting of ultrasonic waves, sonic waves, non-linear mechanical waves, and shock waves, said reaction mixture comprises at least one compound capable of forming a superabsorbent foam.
