Patent number: 5902838Abstract: 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.Type: GrantFiled: October 1, 1996Date of Patent: May 11, 1999Assignee: Loctite CorporationInventors: John G.
