  • A FLEXIBLE FOAM FORMULATION AND METHOD OF PRODUCING THE SAME
    Publication number: 20210284786
    Abstract: Modified 2,4-toluene diisocyanate (2,4-TDI) and 2,6-toluene diisocyanate (2,6-TDI) isomer mixtures and methods of producing the modified TDI isomer mixtures are provided. The modified TDI isomer mixture is a low-cost alternative to expensive commercially available TDI mixtures with high 2,6-TDI ratio, and produce a flexible PU foam with desirable foam properties.

  • Finely divided, cationic or amphoteric, aqueous polymer dispersions, process for their preparation, their use, cationic or amphoteric protective colloids and their preparation
    Patent number: 9481785
    Abstract: A finely divided, cationic or amphoteric, aqueous polymer dispersion which is obtainable by emulsion polymerization of ethylenically unsaturated monomers in the presence of a cationic or amphoteric protective colloid, wherein first the cationic or amphoteric protective colloid is prepared by polymerizing a monomer blend in the presence of at least one first polymerization initiator in an organic solvent, and is carried out in a pressurized reactor at a pressure of at least 1720 kPa and at a temperature of at least 150° C.
    Type: Grant
    Filed: November 22, 2011
    Date of Patent: November 1, 2016

  • FINELY DIVIDED, CATIONIC OR AMPHOTERIC, AQUEOUS POLYMER DISPERSIONS, PROCESS FOR THEIR PREPARATION, THEIR USE, CATIONIC OR AMPHOTERIC PROTECTIVE COLLOIDS AND THEIR PREPARATION
    Publication number: 20130245168
    Abstract: A finely divided, cationic or amphoteric, aqueous polymer dispersion which is obtainable by emulsion polymerisation of ethylenically unsaturated monomers in the presence of a cationic or amphoteric protective colloid, wherein first the cationic or amphoteric protective colloid is prepared by polymerising a monomer blend in the presence of at least one first polymerisation initiator in an organic solvent, and is carried out in a pressurised reactor at a pressure of at least 1720 kPa and at a temperature of at least 150° C.
