Abstract

n-Paraffins of n-C20H42 to n-C50 H102 were epitaxially crystallized on oriented polyolefins; polyethylene, polypropylene, poly-1-butene and poly-4-methyl-1-pentene. In most cases, n-paraffin crystals were epitaxially grown on the substrate surface with the (001) basal plane parallel to it, maintaining a two-dimensional lattice coincidence with the polymer substrate. The epitaxial modes with this orientation were classified into the following three types irrespective of the polymers: 1. (1) (001)p{norm of matrix}SS, 〈110〉p{norm of matrix}FA, 2. (2) (001)p{norm of matrix}SS, [010]p{norm of matrix}FA, 3. (3) (001)p{norm of matrix}SS, 〈110〉 p $ ̊ $ ̌gaFA, where p, SS and FA denote n-paraffin crystals, substrate surface and fiber axis of the polymers, respectively. The angle α depends on the kind of polymer substrate. n-Paraffins longer than n-C40H82 were laid down in parallel on the polypropylene substrate with their axes at a 46° angle with respect to the substrate fiber axis.
