Abstract
Oriented materials are described in which particular crystalline materials are grown on a highly-oriented polytetrafluoroethylene substrate. Compositions are provided comprising a layer of aligned molecular chains of oriented polytetrafluoroethylene and an overlayer of a second polymer that imparts desired properties to the construction. A third layer of crystallizable, orientable material is then deposited on the overlayer. The third layer becomes oriented. The materials are useful as polarizers when the third layer is a polarizing dye.
