  • Radical-curable adhesive compositions, reaction products of which demonstrate superior resistance to thermal degradation
    Patent number: 6342545
    Abstract: The present invention is directed to a radical-curable adhesive composition which includes a (meth)acrylate composition; a thermal resistance-conferring agent; and a radical cure-inducing composition. Reaction products of compositions in accordance with this invention exhibit superior resistance to thermal degradation.
    Type: Grant
    Filed: November 23, 1998
    Date of Patent: January 29, 2002
    Assignee: Loctite Corporation
    Inventors: Philip T. Klemarczyk, Maria L. Masterson
  • Radical-curable adhesive compositions, reaction products of which demonstrate superior resistance to thermal degradation
    Patent number: 6150479
    Abstract: The present invention is directed to a radical-curable adhesive composition which includes a (meth)acrylate composition; a coreactant selected from unsaturated cyclic, bicyclic and tricyclic (meth)acrylates and epoxidized alkyl, cycloalkyl, bicyclic and tricyclic (meth)acrylates; and a radical cure-inducing composition. Reaction products of compositions in accordance with this invention exhibit superior resistance to thermal degradation.

  • Process for the assembly of glass devices subjected to high temperatures, compositions therefor and novel polymers for rheological control of such compositions
    Patent number: 6132548
    Abstract: Cationically curable adhesives and sealants with increased viscosities and improved rheological control and good storage stability are prepared using a cationically curable monomer and a thickening polymer which is the alkylation reaction product of poly(4-hydroxystyrene) or poly(2-hydroxystyrene) with a compound RX where R is allyl, methallyl, crotyl or prenyl and X is Cl, Br or I. The cationically curable monomer suitably includes at least one alkenyloxystyrene monomer. Such thickened adhesives are useful as edge sealants for flat panel display devices. A-stage curing of the adhesive with UV irradiation allows for near ambient temperature fixturing of the device assemblies and B-stage thermal curing of the adhesive can be conducted at much lower temperatures than are needed for glass frit sealants. The B-stage cured products have thermal resistance, outgassing and substrate adhesion properties adequate for flat panel display devices.
