Abstract
The spherulites made from the solution of commercial nylon 6 (Amylan No.1001A, made by Toyo Rayon Co.) were studied by the microscopes. At the first, by the polarization microscope, it was confirmed that the directions of molecular chains were always along the radii (Fig. 1 and 2). Secondarily, by the electron microscope, the directions of molecular bundles were discovered also to be radial (Fig. 3). And the boundary of spherulites were found to be feeble (Fig. 4). The shapes of nuclei looked like the sheaves (Fig. 5 and 6), as those of polyethyleneadipate.
