The yield stress behavior of a range of polyethylene materials which differ with respect to their short chain branch content has been studied. Measurements carried out over a wide range of temperatures have shown that there is a sudden transition in the behavior of the yield stress at a temperature

The deformation behavior of a range of polyethylene materials which differ with respect to both their short-chain branch content and molecular weight has been studied. Mechanical measurements carried out over a wide range of temperatures have shown that there is a sudden transition in the measured t
## Abstract Yield stress of a series of poly(ethylene terephthalate) (PET) filament samples, which differ in molecular draw ratio, was observed at a range of strain rate and temperature to reveal the relation between microstructure and yield stress behavior. Based on the observations, a novel corre
Data on the tensile yield behavior of poly(viny1 chloride) (PVC), reported in the literature, are interpreted in terms of a model involving a cooperative movement of several independent structural units, all with the same activation enthalpy. This analysis leads to physical parameters such as the in
