Silicon-containing Monomer Patents (Class 524/806)
  • Patent number: 10301772
    Abstract: Disclosed are improved carpet products made using certain types of coating compositions to secure carpet fibers to a carpet backing or substrates and/or to secure one or more carpet scrims or other layers to carpet backing. The coating compositions, which can be in the form of either precoating or skip coating compositions, are made from latex binder emulsions based on interpolymers emulsion polymerized from vinyl esters, ethylene, and a multifunctional cross-linking co-monomer such as an unsaturated silane. Such emulsions are also stabilized with surfactant emulsifiers but are substantially free of protective colloid stabilizers. The multifunctional co-monomer alters interpolymer molecular weight, branching and/or flow properties such that films formed from such interpolymers exhibit relatively low elongation values.

    Abstract: Moisture curable compositions including silylated polymers and methods for producing the same are provided. A two component moisture curable system for producing a cured or cross-linked silylated polymer having improved compression set properties is provided. The two component system comprises a first formulation and a second formulation. The first formulation comprises a silylated polymer, water, and filler and the second formulation comprises the silylated polymer, a curing catalyst comprising at least one Brønsted acid, and a moisture scavenger. The final cured formulation may have a compression set, determined by ASTM D395 or ISO 815-1, of less than 100%, and in some examples less than 50% and in some examples less than 15%. This demonstrated improvement in compression set not only allows the silylated polymers to be used in applications where cyclic loads are applied but also enhances product durability.

  • Patent number: 6652634
    Abstract: The present invention relates to graft copolymers, useful as dispersants in ink jet ink compositions, which comprise two structurally distinct segments: a hydrophilic segment and a hydrophobic segment. The preferred hydrophilic segment is comprised preferably of a methacrylic acid polymer, or a copolymer thereof with another monomer, such as styrene sulfonic acid. The preferred hydrophobic segment comprises a polymer or copolymer containing electron rich functional groups comprised of a plurality of methacrylate derivatized monomers, preferably a methacrylate ester monomer, or a substituted methacrylate ester monomer (a methacrylate ester where the alkyl group is replaced with a siloxyl substituent, an oligomeric siloxane). The present invention also relates to aqueous ink compositions which include the polymeric dispersants of the present invention. A further embodiment of the present invention comprises a polymer comprising a monomeric hydrophobic head and a polymeric tail.
