Abstract: | A structural study of nylon 13,13 has been carried out by means of X-rays and electron microscopy. Both X-ray and electron diffraction data, obtained from oriented films as well as from lamellar crystals prepared in solution, evidenced that nylon 13,13 adopts a structure in a monoclinic lattice of parameters ao=0.488 nm, bo=0.473 nm, co=3.40 nm, = =90°, =121°. As expected from the constitution of the nylon, no trace of structure with chains in fully extended conformation ( -form) was observed throughout this study. |
