The Stress-Optical Coefficient and Amorphous Order,

Abstract

The calculated stress-optical coefficients obtained using the rotational isomer model and the principle of additivity of bond polarizability tensors give values of the segment polarizability anisotropy, Delta Gamma sub S, in reasonable agreement with experimental values for swollen rubber networks. Furthermore, these values agree well with those obtained from streaming birefringence studies. Estimates of the effect of ordering in the amorphous state upon Delta Gamma sub S lead to values appreciably in excess of those found experimentally.
