| Abstract: | Monolayers of certain surface-active diacetylene compounds were polymerized at the gas—water interface and collapsed to self-supporting fibers. The monolayer fibers were found to have an unusual morphology in that while the polymeric backbones have a random orientation, the hydrocarbon side chains are all perpendicular to the fiber axis. The fiber d spacings determined from x-ray diffraction agree well with electron diffraction data from unperturbed polymeric monolayers. Tensile tests of the monolayer fibers indicate average strength and high modulus. |
