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).
Claims14
A process for producing a surface-functionalized molding (oF) having a functionalized surface (fO), comprising the steps of
- i) providing a molding (F) having a surface (0) which comprises a polyamide (P), the polyamide (P) comprising diene units of the general formula (I)
- in which
- R1 and R2 independently of one another are selected from C1-C10 alkanediyl,
- ii) contacting the surface (O) of the molding (F) provided in step i) with a dienophile-containing solution (dL) which comprises at least one dienophile, the at least one dienophile comprising at least one dienophile unit which is reactive toward the diene units (I) present in the polyamide (P), to give the surface-functionalized molding (oF) having the functionalized surface (fO).
