Rheo‐optical Fourier‐transform infrared (FTIR) spectroscopy in combination with Atomic Force Microscopy (AFM) was used to clarify the correlation between the morphology and the mechanical properties of two groups of heterogeneous polymers: different styrene‐ block ‐butadiene‐ block ‐styrene triblock copolymers and a dynamic vulcanizate based on polypropylene/ethylene‐octene‐copolymer. In all the polymers investigated the soft phase always oriented more than the hard phase. The degree of orientation in different phases depended on the nature of the phases as well as on the stress distribution in correlation to the morphology and their alignment. The observations at the molecular level corresponded well with the results from morphological studies at the microscopic level, which, in fact, enables an extensive and complex understanding of the structure‐properties correlation of these types of polymers.
