  • Publication number: 20140353363
    Abstract: Disclosed is a customizable, preformed decorative wrapper. The device includes a wrapper with a central region and a plurality of sections extending radially outward therefrom. In one embodiment, additional sections may be removably attached to one or more free ends on the central region, wherein the additional sections may be substantially equal in shape and dimensions as existing sections disposed around the central region. The wrapper and the additional sections each include a defined perimeter having an adhesive material therearound, and a removable backing thereon. The wrapper and the additional sections may be constructed from a transparent heat-shrinkable substrate, for example, vinyl or polyvinyl chloride, which can easily bond with graphical or decorative ink so that the ink is prevented from separation from the substrate. In this way, the present invention is may comprise customized designs printed directly thereon by means of an inkjet or a laser printer.

  • Patent number: 6329207
    Abstract: A wet chemical indicator for peracetic acid solutions includes an indicator for peracetic acid and an inhibitor.

  • Patent number: 5401807
    Abstract: A method has been discovered for generating free radicals at saturated carbon atoms on the backbone of acrylate polymers or copolymers. This method is useful for combining at least two polymer chains at the free radical sites on each polymer chain to form a polymer or copolymer product with increased molecular weight and a controlled degree of branching. The polymers and copolymers produced by this process are useful as antiscalants, dispersants, incrustation inhibitors and superabsorbants. They are particularly useful in detergent and cleaning applications.

  • Patent number: 5130369
    Abstract: Functionalized polymeric compositions are prepared by polymerizing ethylenically unsaturated functional monomer in a solvent including a reactive compound. The functional groups of the reactive compound and the functional monomer react during or subsequent to the polymerization of the functional monomer to provide functionalized polymeric composition. The reactive compound can be a hydroxy-terminated, poly(ethleneoxy)ated hydrophobe-bearing compound and the functional monomer can be a polymerizable carboxylated monomer, the functionalization in this case being a condensation. Removal of the water of condensation by azeotropic distillation drives the reaction to completion. The resulting high solids functionalized polymeric composition is soluble or dispersible in an appropriate solvent, and can be used as is, diluted with a solvent, or isolated.

  • Patent number: 5100980
    Abstract: This invention relates to copolymers containing as copolymerized monomer units aliphatic monoethylenically unsaturated dicarboxylic acids such as maleic acid, monoethylenically unsaturated monocarboxylic acids such as acrylic acid and carboxyl-free monoethylenically unsaturated monomers such as alkyl esters of acrylic acid. This invention particularly relates to the use of low levels of copper ions in an aqueous polymerization process to promote copolymerization of the above-mentioned monomers at high conversion while maintaining and improving molecular weight control. These copolymers are useful primarily as antiscalants, dispersants, hard surface cleaners, detergent builders and incrustation inhibitors.
