Abstract

Comparative X-ray and neutron reflectivity (XR and NR) measurements were made to study interface formation in the highly immiscible polymer pair deuterated polystyrene/polybromostyrene (PS/PBrS). Since deuterium provides the scattering contrast for NR while electronic density differences give XR contrast, the experiments constitute independent high-resolution measurements of the same interface. For the (PBrS) (670K)/dPS(730K) interface we find the interfacial width, 39 ± 5 Å by XR and 41 ± 5 Å by NR to be in satisfactory agreement.
