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 an agricultural film (AF) comprising at least one copolyamide, wherein the copolyamide has been prepared by polymerizing at least one lactam and a monomer mixture (M). The present invention further relates to a process for producing the agricultural film (AF) and to the use of the agricultural film (AF) as mulch film, as silage film, as greenhouse film or as silo film.

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.
