  • Dispersible wet wipes
    Patent number: 8133825
    Abstract: A wet wipe comprises a nonwoven material. The nonwoven material comprises a fibrous material and a binder composition. The binder composition includes a cationic ion-sensitive emulsion polymer, which can comprise the emulsion polymerization product of at least one hydrophobic monomer which has been stabilized by a solution-polymerization-derived cationic ion-sensitive polymer stabilizer. In some aspects, a solution-polymerization-derived cationic ion-sensitive polymer binder can be solution blended with the already-formed cationic ion-sensitive emulsion polymer to provide additional benefits. In other aspects, the solution-polymerization-derived cationic ion-sensitive polymer binder is the same as the s-solution-polymerization-derived cationic ion-sensitive polymer stabilizer.

  • Method for preparing a flexible superabsorbent binder polymer composition
    Patent number: 7335713
    Abstract: A process of making the flexible superabsorbent binder polymer composition includes preparing a preneutralized monomer solution having at least about 40 mol % degree of neutralization, preparing a monomer solution including monoethylenically unsaturated monomers, one of which includes an alkyloxysilane functionality, preparing initiator system solutions and adding the solutions to the monomer solution, mixing the foregoing solutions into a polymerization solution, cooling the polymerization solution, and post neutralizing the polymer.
