Abstract:

Adhesive compositions are described which consist of an adhesive base as a first part and an initiator portion as a second part, said first part consisting essentially of (a) 100 parts by weight of a polymerizable monomer having at least one. alpha. ,. beta. -unsaturated carboxyl functionality; (b) as an accelerator, about 0. 05 to 20 parts by weight of a compound selected from the group consisting of organic sulfimides and perfluoroalkylsulfonanilides; and (c) an inhibitor of free-radical polymerization; and the second part comprising a condensation reaction product of an aldehyde and a primary or secondary amine. These compositions may be formulated as adhesives which, for example, exhibit pressure-sensitive properties, which are particularly suitable in hot-melt applications, or which are particularly suitable as structural adhesives. Bonding methods are also described herein.
