  • Patent number: 6300410
    Abstract: There is provided a polymer useful in coating, ink and adhesive compositions. The polymer has monomeric units derived from a monomer having the formula: wherein: R1 is alkylene having about 2 or 3 carbon atoms; R2 is alkylene having about 2 to about 10 carbon atoms; X is oxygen, sulfur, or NR3 wherein R3 is hydrogen, alkyl, alicyclic, aryl, heteroalkyl, heterocyclic; R4 has the structure of the residue of an alicylic diisocyanate wherein the isocyanate groups have reactivities that differ one from another; Y is oxygen, sulfur, or NR5 wherein R5 is hydrogen, alkyl, alicyclic, aryl, heteroalkyl, or heterocyclic; R6 is alkylene, arylene, aralkylene, alkarylene, or heteroalkylene; Z is oxygen, sulfur, or NR7 wherein R7 is hydrogen, alkyl, alicylic, aryl, heteroalkyl, or heterocyclic; and R8 is hydrogen or methyl. The polymer is further comprised of monomeric units from at least one other polymer. Further disclosed is a latex of the polymer and paints, inks or adhesives having the latex.

  • Patent number: 6069275
    Abstract: A novel monomer composition for promoting wet adhesion of latex polymers for paints is provided. The composition consists essentially of a monomer having the formula: ##STR1## The preferred monomer is derived from the reaction of hydroxyethyl methacrylate with isophorone diisocyanate followed by reaction of the monourethane product the N-aminoethyl ethylene urea. The monomer is preferably copolymerized in an emulsion polymerization with acrylic and/or vinyl monomers.
