  • ANIONIC CROSS-LINKED POLYMERS IN WATER-IN-WATER POLYMER DISPERSIONS
    Publication number: 20120214930
    Abstract: The present invention relates to water-in-water polymer dispersions containing cross-linked anionic polymers, methods for their preparation and their use. The water-in-water polymer dispersions are useful inter alia as flocculants, dewatering (drainage) aids and retention aids in papermaking.

  • BIMOLECULAR INVERSE EMULSION POLYMER
    Publication number: 20120101194
    Abstract: The invention relates to novel, stable bi-molecular cationic inverse emulsion polymers (W/O) with both different molecular weights and cationic activities that are assembled via an “in situ” emulsion polymerization of a high molecular weight cationic polymer in the presence of a low molecular weight polymer in the aqueous phase. The low molecular cationic polymer is produced in a pre-polymerization in solution. The novel, stable cationic water-in-oil emulsion is easy invertible and useful as flocculant, dewatering aid and retention aid in papermaking.
