The deformation of linear polymers polymers was investigated from three viewpoints 1 the microscopic, involved measurements of free volume and the relationship of the intermolecular forces to the yield point, 2 the phenomenological, involved the prediction of non-linear viscoelastic programs of deformation in terms of the creep curves, and 3 environmental crazing at low temperatures, involved the effects of gases on the tensile deformation. Experiments and theories concerning these three viewpoints are presented.
