To elucidate the mechanism of high speed tensile fracture of polymeric substances the fracture energy, W, is compared with the integrated loss tangent, L, obtained by integrating the loss tangent from 0°K to the temperature at which W was measured. W was determined by the oscillograph of flywheel type high speed tensile tester (testing speed 5m/sec). W is almost proportional to L for ten straight polymers except polycarbonate (PC), while the increase of W is more marked than that of L and the proportionality does not hold for PC and the blend polymers of polyvinylchloride with impact-resisting material, i.e., methyl methacrylate-butadiene-styrene graft copolymer.
