Structural analysis of transferred monolayers of high-molecular-weight polyvinyloctadecyl ether

Abstract

The pressure area ( π A) characteristics of high-molecular-weight polyvinyloctadecyl ether, 7-hydroxy-4-heptadecyl coumarin, and mixtures of the two at the air/water interface are reported, along with limiting areas for these systems. Electron diffraction results of cast monolayer films of these materials are also present. Analysis of the diffraction rings reveal that the molecular packing on the cast film is in the form of a hexagonal array with some long-range ordering present. © 1985.
