Abstract
Thermosettable PSA compositions of the invention comprise a major proportion of the adhesive component of at least one acidic polymer and at least one amine-containing compound capable of reacting with acidic functional groups on the acidic polymer to cure the thermosettable PSA composition into a thermoset adhesive. The thermosettable PSA compositions are particularly useful for forming semi-structural or structural bonds. Thermoset adhesives therefrom and methods of forming the thermoset adhesives are also disclosed.
