  • Patent number: 5047463
    Abstract: Cast ceiling tile requires a particular rheology of its wet formulation for the dried tile to have a desired aesthetic appearance. The use of a latex binder rather than starch for cast ceiling tiles imparts the necessary rheological properties to the wet ceiling tile formulation. The tile is prepared by blending mineral wool with a premixture of water, latex, and filler, said premixture having a sharp yield point when measured with a recording Brookfield Viscometer. The latex is an alkali-swellable latex comprising (i) a C.sub.3 -C.sub.8 .alpha.,.beta.
    Type: Grant

  • Patent number: 4816518
    Abstract: Substantially solid state thermoplastic thermal radiation suppressor composition for suppressing thermal radiation transmission comprise a thermoplastic substance (e.g., a polymer of polymerized styrene, methyl methacrylate and 2-isopropenyl-2-oxazoline) in intimate contact with a composition (e.g., a polymer of polymerized ethylene and acrylic acid) which exhibits a refractive index essentially equal to that of said thermoplastic substance at one temperature but a refractive index different from that of said thermoplastic substance at another temperature. The thermal radiation suppressor compositions exhibit good physical properties and can be employed in the form of thermoplastic sheets or films. The compositions are useful as devices in greenhouses, skylights, etc.

  • Patent number: 4644032
    Abstract: A pressure-sensitive adhesive having non-ghosting characteristic comprising a latex of polymers having pendent oxazoline groups, coreactive groups and a tackifier. The latex comprises discrete polymer particles having both pendent oxazoline and coreactive groups or a blend of discrete polymer particles one portion of which has pendent oxazoline groups and the other portion of which has pendent coreactive groups. The oxazoline group is preferably 2-isopropenyl-2-oxazoline and the coreactive group is a carboxyl, sulfonic acid, anhydride, phenolic, hydroxyl, amide or amine group.
