Abstract

The invention relates to a hot-melt adhesive composition comprising a thermally reversible crosslinked polymer network comprising at least one acid anhydride functionalized polymer and at least one crosslinking agent, and at least one at 25 °C solid non-functionalized thermoplastic polymer. The invention is also related to a method for producing the hot-melt adhesive composition, to the use of the adhesive composition as an assembly adhesive, laminating adhesive, or as adhesive for building of sandwich elements, to a method for bonding substrates to each other, and to a composite element produced by using the adhesive composition.
