Thermosetting adhesive and sealing compositions are described, consisting of: (a) 70 to 95 wt.-% of polyesters with a glass transition temperature below 20 DEG C., mixed in some cases with a polycarboxylic acid anhydride, (b) 5 to 30 wt.-% of polyoxazolines which contain at least 2 oxazoline groups per molecule, the polyoxazolines being suspended in the polyesters, (c) 0 to 4 wt.-% of paraffin and (d) optionally additional 1 to 50 weight-percent of the total amount of the components, of reactive or nonreactive diluents and/or additives and/or fillers. |
