The global orientational order that develops in polycarbonate under plastic deformation has been measured quantitatively by CSA and dipolar DECODER experiments. The results are in substantial agreement with the predictions of an affine entanglement network model. Athermal atomistic simulations, on the other hand, tend to overestimate the orientational order.

Abstract

The global orientational order that develops in polycarbonate under plastic deformation has been measured quantitatively by CSA and dipolar DECODER experiments. The results are in substantial agreement with the predictions of an affine entanglement network model. Athermal atomistic simulations, on the other hand, tend to overestimate the orientational order. The orientation behavior in glassy polycarbonate seems to be essentially the same as that in the melt.
