  • Patent number: 9790394
    Abstract: The present invention provides an aqueous floor coating composition comprising: (A) water; (B) at least one supramolecular polymer; and (C) optionally, one or more additional ingredients. The supramolecular polymer (B) comprises polymerized units derived from: (1) one or more 4H monomers which comprise a polymerizable group and a quadruple hydrogen bonding (4H) moiety; (2) at least one monomer having acid functional groups; and (3) one or more ethylenically unsaturated monomers. In a preferred embodiment, the supramolecular polymer comprises 4H monomers derived from reaction of an isopropenyl alpha,alpha-dimethylbenzyl isocyanate (TMI) and 2-amino-4-hydroxy-6-methylpyrimidine (MIC), as well as acid functional monomers selected from (meth)acrylic acid, and ethylenically unsaturated monomers comprising butyl acrylate, methyl methacrylate, and styrene.
