Lamellar liquid crystals of lecithin and 2-hydroxyethyl methacrylate (HEMA) were polymerized by using UV radiation. Optical microscopy, infrared spectroscopy, and small-angle X-ray diffraction were used to compare the structure prior to and after polymerization. The lamellar structure was retained after polymerization with increased interlayer spacing.

Non-aqueous birefringent microemulsions were found in a system ofp-xylene, glycerol, triethanolammonium oleate and oleic acid. The microemulsions showed long term stability once formed, but failed to form spontaneously when the components were contacted. After partial separation by centrifugation, no signs of spontaneous reformation were found.
