The results show that the mechanical properties of this PMMA depend strongly on the testing temperature. The Young's modulus and flow stress were found to decrease with increasing temperature at low strain rate. At the strain rate of 10^(-1) 1/s, strain soften was observed under all experiment temperatures. At high strain rate, with the temperature increase, the flow stress deceases remarkably while the failure strain increases, and the strain softening was also observed at the temperature above 333K.
