The preparation of filled two‐component semi‐interpenetrating polymer networks (semi‐IPNs) is described and the results of an investigation of their morphology by means of dynamic mechanical spectroscopy are considered. The influence of an active dispersed filler (γ‐Fe 2 O 3 ) on the semi‐IPNs phase structure is studied. A comparison is made between filled and unfilled semi‐IPNs consisting of compatible or incompatible polymers. In the case of a semi‐IPN of compatible polymers, the introduction of γ‐Fe 2 O 3 was observed to cause phase separation. With a two‐phase semi‐IPN the introduction of the filler enhanced the phase separation. The presence of two distinct peaks (the dynamic glass transition temperatures) corresponding to those of the two initial homopolymers shows the semi‐IPN to have a two‐phase structure.
