Abstract
We introduce a tensor variable to describe chain deformations in the continuum limit. Then we set up a dynamic model and apply it to the problem of phase separation in polymer solutions under shear. Effects of chain deformations are shown to be crucial in the entangled case. A large shear-demixing effect is found in semidilute solutions in agreement with experiments.Keywords
