Abstract Simultaneous two‐component interpenetrating polymer networks (IPNs) of polyurethane (PU)–poly(methyl acrylate) (PMA) were prepared, as well as the corresponding pseudo‐IPNs. A comparison was made between the full IPNs, pseudo‐IPNs, and the respective homopolymers. Their ultimate mechanical properties were obtained and the dynamic glass transition temperatures ( T g 's) were found using a thermomechanical analyzer. At all compositions, a single T g (except 50–50 wt %) was found.
