Herein, the synthesis and characterization of new functionalized block copolymers is reported. The polymer materials consisting of a polar block with acid groups and a nonpolar block with alkyne units show a strong tendency of phase segregation. Techniques like NMR, GPC and DSC were applied to verify structure, molar masses, molecular weight distributions and thermal properties. Thin films of these polymers show a distinct surface patterning of mesoscopic dimension. Furthermore, phase separated photosensitive block copolymers were designed and the fabrication of self assembled and additionally photopatternable polymer surfaces is demonstrated.
