    Abstract: One- and two-part spray non-isocyanate foams that include an amide-based oligomer containing pendant carboxylic acid and a polyfunctional aziridine crosslinking agent is provided. The amide oligomer typically contains urea links, urethane links or both groups. Additionally, the foams may include one or more plasticizer, a non-functionalized resin, a surfactant, and/or a thickening agent or rheology modifier. The amide oligomer does not contain any isocyanate groups, and, as a result, there are no free isocyanate moieties generated during formation of the foam that may be potentially hazardous to workers installing the foam. The presence of the urethane segments on the oligomer permits for the generation of a polyurethane foam without the drawbacks of conventional polyurethane foams. The foams may be used to fill cavities, cracks, gaps and crevices, such as around windows and doors, and may also be used in flash and batt systems.

  • Patent number: 7875182
    Abstract: Size-selective hemocompatible porous polymeric adsorbents are provided with a pore structure capable of excluding molecules larger than 50,000 Daltons, but with a pore system that allows good ingress and egress of molecules smaller than 35,000 Daltons. The pore system in these porous polymeric adsorbents is controlled by the method of synthesis so that 98% of the total pore volume is located in pores smaller than 300 Angstroms (?) in diameter with a working pore size range within 100 to 300 ? in diameter. The porous polymeric adsorbents of this invention are very selective for extracting midsize proteins, such as cytokines and ?2-microglobulin, from blood and other physiologic fluids while keeping the components required for good health such as cells, platelets, albumin, hemoglobin, fibrinogen, and other serum proteins intact.

  • Patent number: 7807729
    Abstract: A production process for heat-expanded microspheres includes the step of providing a gaseous fluid containing heat-expandable microspheres, which includes a shell of thermoplastic resin and a blowing agent encapsulated therein having a boiling point not higher than the softening point of the thermoplastic resin and have an average particle size from 1 to 100 ?m. The gaseous fluid is fed through a gas-introducing tube having a dispersion nozzle on its outlet that is fixed inside a conduit having a hot gas flow flowing therethrough. A jet of the gaseous fluid is emitted through the dispersion nozzle. Further, the gaseous fluid is collided on a collision plate fixed under the dispersion nozzle so as to disperse the heat-expandable microspheres in the hot gas flow. The dispersed heat-expandable microspheres are heated in the hot gas flow at a temperature not lower than their expansion initiating temperature and thus expanded.

  • Patent number: 7803849
    Abstract: The present invention is to solve conventional problems, namely, that when an attempt is made to obtain a thick, in-mold foamed molded article with excellent fusibility between beads formed from an acrylic resin expanded beads, cooling takes an extremely long time and production efficiency is poor, and to provide acrylic resin expanded beads with which an in-mold foamed molded article with excellent fusibility between expanded beads can be manufactured in a short cooling time even with a thick foamed molded article such as a block foamed molded article, and the molding cycle can be improved. The acrylic resin expanded beads of the present invention are expanded beads in which an acrylic resin serves as a base resin, and the bead surfaces have continuous ridges in a mesh pattern.

  • Patent number: 7629394
    Abstract: The present invention describes a process of preparing microcapsules in a UV curable water immiscible phase. The microcapsules formed according to the invention contain an aqueous phase core. The process comprises dispersing a water soluble or dispersible core material along with at least one wall forming prepolymer and a polycondensation polymerization catalyst into an aqueous solution. The aqueous phase is then dispersed into the water immiscible phase comprising UV curable monomers or oligomers forming droplets of the aqueous phase solution in the water immiscible phase. Polycondensation of the prepolymers is initiated to form polymeric wall material or microcapsules at or near the interface of the water immiscible solvent and droplets of aqueous phase solution. Following capsule formation, a UV initiator is dispersed in the water immiscible phase. The UV curable dispersion containing aqueous microcapsules can be coated on a substrate.
