  • Coating compositions having chelant functionality
    Patent number: 9845408
    Abstract: The present invention provides a floor coating composition comprising (A) and aqueous solvent; and (B) a chelating polymer which comprises units derived from one or more aminocarboxylate compounds or their salts, one or more other polymerizable monomers, one or more ethylenically unsaturated monomers and, optionally, one or more crosslinking monomers. For example, the aminocarboxylate compounds or their salts may be one or more of iminodiacetic acid (IDA), iminodisuccinic acid (IDS), ethylenediamine triacetic acid (ED3A) and ethylenediamine disuccinic acid (EDDS), or their salts. Suitable polymerizable monomers may be one or more of glycidyl methacrylate (GMA), allyl glycidyl ether (AGE), vinylbenzyl chloride (VBC), allyl bromide, and their derivatives.
    Type: Grant
    Filed: February 22, 2013
    Date of Patent: December 19, 2017
    Assignee: Rohm and Haas Company
    Inventors: Afia Sarpong Karikari, Theodore Tysak

  • Aqueous coating composition
    Patent number: 8686081
    Abstract: An aqueous coating composition containing a polymer which contains calcium or magnesium and polymerized residues of three monomers. The first monomer is a complexing monomer having a log stability constant for calcium or magnesium from 0.3 to 4. The second monomer is methacrylic acid. The third monomer is a crosslinker.
