Professor Benjamin Widom is funded by a grant from The                       Theoretical and Computational Chemistry Program to perform                      theoretical and experimental studies of phase-separated dilute                  high-polymer solutions, particularly the structure and polymer                  conformation at the interface.   This fundamental theoretical                   research will lead to an improved understanding of the                          properties of polymer solutions, and their dependence on the                    molecular properties of the polymers which comprise them.                                                                                                          The theoretical model used for these studies has been shown                  by Widom to be equivalent to the Ising-spin model with                          many-body and further-neighbor interactions.  The proposed                      studies of this lattice microemulsion model will emphasize                      generalized amphiphile-amphiphile interactions, unsymmetrical                   states, and the correlation, structure, and scattering                          functions.  The theoretical studies of these solutions will be                  directed toward obtaining the interfacial structure, including                  the spatial dependence of the polymer-chain geometry in the                     interface.
