Glassy crosslinked networks were prepared by copolymerization of methyl methacrylate with up to 5.2 mole‐percent of ethylene and triethylene dimethacrylates. The moduli of these materials were measured by tensile and two dynamics methods: forced resonance vibration and ultrasonic. Impact strength were measured using the Izod geometry and Sharpy notched samples to induce brittle fracture. The increase in the length of the crosslinking agent caused an increse in the deformability and impact strength of these materials without any effects in the moduli.
