The production of metal‐based hybrid laminates, such as aluminum combined with thermoplastics like polyamide 6, requires a precise and purposeful design of the interface between the two components. The utilization of twin polymerization has been successfully examined and an improved adhesion behavior is shown. By utilizing the monomers 2,2′‐spirobi[4 H ‐1,3,2‐benzodioxasiline] and 2‐(3‐amino‐ n ‐propyl)‐2‐methyl‐4 H ‐1,3,2‐benzodioxasiline in a molar ratio of 15:85, medial tensile shear strength values of 12.9 ± 3.9 MPa are achieved in tests according to DIN EN 1465. Electron microscopic and atomic force microscopic investigations give further structural details of the hybrid material. Additionally, the results of nanoindentation and microscratch tests clearly demonstrate that the choice of an adhesion promoter depends on its chemical as well as its mechanical characteristics.
