Abstract
A new poly(ester amide) derived from β-alanine, 1,12-dodecanediol, and sebacoyl chloride has been synthesized and its crystalline structure studied using transmission electron microscopy and X-ray diffraction. The polymer crystallizes according to an orthorhombic unit cell with parameters a = 4.80 A, b = 7.58 A, and c (chain axis) = 38 A. Simulation of the electron diffraction patterns indicates a molecular arrangement that combines features of polyamides and polyesters. Like the α and β forms of nylons, intermolecular hydrogen bonds are established along a single direction that runs parallel to the a crystallographic axis (4.80 A). On the other hand, as the majority of polyesters, the primitive unit cell is constituted by two molecules with different setting rotation angles about c.
