Studies on fatigue of solid polymers have been approached along two distinct paths; one is phenomenological studies such as the detailed examinations of crack nucleation and crack propagation, and the other approach involves molecular considerations, being associated with bond breakage, chain orientation and so on. In clarifying the fatigue characteristics of polymeric materials, it is also important to investigate the variation of viscoelasticity during the fatigue process. In this paper, the variation of dynamic viscoelastic properties during fatigue process are measured at various ambient temperatures and imposed strain amplitudes. The data are effective in clarifying the fatigue mechanisms and proposing the fat criteria for solid polymers. Detailed description is made on plasticized poly(vinyl chloride) as a typical case.
