Publication number: 20140353363Abstract: 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.Type: ApplicationFiled: July 30, 2014Publication date: December 4, 2014Inventor: Kathleen Hughes

Patent number: 5401807Abstract: A method has been discovered for generating free radicals at saturated carbon atoms on the backbone of acrylate polymers or copolymers.

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.Type: GrantFiled: October 8, 1992Date of Patent: March 28, 1995Assignee: Rohm and Haas CompanyInventors: Kathleen A.

Patent number: 5130369Abstract: 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.Type: GrantFiled: January 10, 1990Date of Patent: July 14, 1992Assignee: Rohm and Haas CompanyInventors: Kathleen A.
