Abstract: A method prepares a curable composition based on ground composite material from the recycling of discarded composite elements such as old pipes or rotor blades of wind power plants. The ground composite material allows for the replacement of virgin short glass fibers and fumed silica commonly employed in such compositions used as structural adhesives essentially without any negative impact on the performance.

Abstract: The present invention relates to a process for producing a surface-functionalized molding (oF) having a functionalized surface (fO). In this process a surface (O) of a molding (F) is brought into contact with a dienophile-containing solution (dL). The surface (O) comprises a polyamide (P) which comprises furan units. These furan units are able to react with the at least one dienophile present in the dienophile-containing solution (dL) to give the surface-functionalized molding (oF) having the functionalized surface (fO).

Abstract: The present invention relates to a process for preparing a crosslinked polyamide (vP) by providing a melt (S), which comprises at least one polyamide (P) containing furan units and at least one dienophile at a first temperature T1, and cooling the melt (S) subsequently to a second temperature T2 which is below the melting temperature TM of the at least one polyamide (P), to give the crosslinked polyamide (vP). The present invention further relates to a crosslinked polyamide (vP) obtainable by the process of the invention.
