Claim Text:
1. A reactive melt adhesive comprising two separately present components A and B each containing one or more polymers A or B having different functional groups, wherein these groups can react with one another under the influence of temperature, and the functional groups reactive with one another are selected from hydroxy, amine, carboxylic acid, anhydride, epoxy groups, nonreactive polymers and/or additives are contained in at least one of the components, the components are present in physically separated regions, wherein the adhesive exhibits a first temperature in a range between 80 and 150° C. in which the components melt and are miscible with one another but the functional groups do not react with one another, the adhesive exhibits a second temperature range between 130 and 190° C. in which it can melt and chemically crosslink, wherein the second temperature is above the first temperature.
