Notes:
A simple theory is developed which correlates the Izod impact strength of polymers with (G′100-G′300)2/G′100, where G′100 and G′300 are dynamic shear moduli at 100°K. and 300°K., respectively. The theory assumes the Maxwell element for the material and the fracture time smaller than the relaxation time. The theory is verified by experimental data for numerous polymers. Another approach which correlates the impact strength with the integrated loss factor from 0 to 300°K. is also proved valid.
