摘要：

The crystallization behaviour of polyethylene, of the amylose-alcohol-complexes and of the amylose-iodinecomplex is compared. Polyethylene and the amylose-alcohol-complexes are similar; flat single crystals or crystallites are formed. The temperature dependence of the foldlengths and of the crystal diameters is lower than expected by the kinetic theory of Lauritzen and Hoffman. It is proposed, that these deviations are due to the temperature dependence of chain stiffness of the coiled molecules in solution. With the amylose-iodine-complex only fibrils are formed. One can get single rodlike molecules with a uniform diameter of 40 Å. © 1969 Dr. Dietrich Steinkopff Verlag.
