Elasticity of Model Poly(oxypropylene) Networks

The equilibrium stress-strain properties and the swelling behavior of moderately cross-linked model networks of poly(oxypropylene) were studied. Results were in general agreement with the theory of rubber elasticity due to Flory. However, data on the highly cross-linked networks (M?c ? 725) could not be satisfactorily described by the recent theories of elasticity or swelling. This is believed to be primarily due to the marked non-Gaussian character of the very short network chains and the substantial chemical modification of the polymer by the cross-linking moiety which inevitably occurs at high cross-link densities.
