摘要：

Birefringence has been measured on yielded specimens of polycarbonate in simple tension in creep and stress relaxation. The pseudo-affine and random-chain affine models both fail to describe the experimental relationship between birefringence (or orientation) and strain. A new model assuming affine deformation of chain ends and non-random chains is presented, adequately describing the trends of experimental data.
