The mechanical behavior of polyurethane‐poly(methyl methacrylate) interpenetrating polymer networks (PUR/PAc IPN's) was investigated. Stress‐strain and impact resistance measurements were made on IPN's with a variable PUR content. The effect of the degree of crosslinking of each network on the mechanical properties was also studied. It appears that only the ultimate elongation varies largely upon changing the crosslink degree. The results are interpreted in terms of the contribution of each network to the mechanical behavior, but also by the interpenetration of both components and by the phase continuity of the PAc network.
