Abstract
Although it has been known for many years [1] that a large number of natural and synthetic high polymers are partially crystalline in nature, it was not until 1957 that the techniques for producing isolated polymer single crystals became generally known. In that year Keller [2], Fischer [3], and Till [4] independently prepared single crystals of polyethylene (PE) from dilute solution. Since then single crystals of many other types of polymers have been prepared by dilute solution methods. Despite differences in chemical structure and molecular packing, these single crystals possess many common characteristics [5]. Isothermally grown dilute solution crystals are generally platelike in nature, with lateral lamellar dimensions of the order of microns and a lamellar thickness, ℓ, of the order of 100 Å. From electron diffraction studies it is known that the c-axis or chain direction is, in most crystals, essentially perpendicular to the lamellar surfaces.
