  • 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.

  • Patent number: 5061523
    Abstract: An effective autodeposition bath with low volatile organic compound emissions can be compounded with polymer solids made by polymerizing a mixture of monomers consisting of certain acrylates and other monomers. E.g., a suitable mixture is, in percents by weight, 44% butyl acrylate, 36% acrylonitrile, 10% styrene, 7% methacrylic acid, 2% of the methyl ether of methacrylamide, and 1.5% of hydroxyethyl acrylate.

  • Patent number: 4012437
    Abstract: An improved method is provided for producing polymers of organic compounds, such as ethylenically unsaturated monomers, containing a betaine-type group of the formula: ##STR1## The method involves the reaction of acrylic acid or aqueous methyl acrylate and an aminoalkyl (meth)acrylate or an N-amino-alkyl (meth)acrylamide having a basic tertiary nitrogen atom in the presence of a free radical initiator. The monomers undergo vinyl addition polymerization to form valuable polymers having a wide variety of uses, such as flocculants, retention aids in the deposition of polymers, pigments, etc. on the fibers in a paper pulp, e.g., in the formation of mineral-filled papers.

  • Patent number: 3992333
    Abstract: The present invention is concerned with new and improved binders for the production of foamed or cellular articles which have a high degree of absorbency, and retain their bonded character as well as absorbency through numerous wash-dry cycles. The cellular articles are bonded by a novel self-cross-linking binder comprising a copolymer of (a) N-methylol-amine or -amide units, (b) sulfonic acid units which contain no basic nitrogen atoms or group, and (c) certain acrylic units of neutral but mildly hydrophilic character which contain no basic nitrogen atoms or group.
