The viscoelastic properties of several hypothetical multiphase polymeric materials were investigated in relation to their phase‐property dependencies and microstructures. Theoretical mechanical considerations based on the self‐consistent interlayer model were performed to point out that specific geometrical arrangements into phases of a set of properties of the pure constituents can lead to interfacially induced damping peaks in dynamic mechanical spectra (DMS). Such additional contributions in DMS were referred to micromechanical transitions to distinguish them from ordinary molecular transitions.
