H. Kim et Wc. Zin, MOLECULAR PACKING OF POLY(AZOMETHINE)S HAVING FLEXIBLE (N-ALKYLOXY)METHYL SIDE-CHAINS IN FILMS, Polymer bulletin, 39(6), 1997, pp. 701-705
The molecular packing of poly(azomethine)s having (n-alkyloxy)methyl s
ide chains in films was studied by wide-angle X-ray scattering. Soluti
on-cast films on silicon wafer and melt-sheared films show the same ty
pe of molecular packing, i.e. the main chain layers are aligned parall
el to the film surface but the main chains are macroscopically isotrop
ic in the film surface plane. In the melt-sheared films, the shear doe
s not orient the main chains but the main chain layers, which can be e
asily understood by their geometric shapes.
