Abstract: Semi-and fully-interpenetrating polymer networks (IPN) based on polyurethane/MMA were prepared. The effects of component ratio, amount of cross-linking agent and the structure of the semi-and fully-IPN on mechanical properties were observed.The δp and Mc of the IPN were determined by means of swelling measurement.Experi-mental results indicated that Mc is an important factor influencing physical proper-ties of IPN system.
