Abstract
We define local order parameters to take into account the orientation of monomers and molecules in polymer systems. These fields are naturally coupled to density gradients. Such couplings lead to interesting effects in the neighbourhood of interfaces (polymer-solvent and polymer-polymer cases are considered) : macromolecules are prolate on one side, oblate on the other.
