Random polyesteramides with different chemical compositions and block polyesteramides have been prepared by a two-step polycondensation method from adipolyl dichloride, 1,10-decandiol, and 1,6-diaminohexane. A sample of alternating microstructure has been synthesized by melt polycondensation of 1,10-decandiol and preformed bisesteramides. The thermal and viscoelastic behavior has been investigated and related to the chemical composition and chain microstructure. The random copolymers exhibit one transition in the crystalline phase, whereas two transitions are shown by the block copolymers. The viscoelastic behavior suggests that in the amorphous component a partial microsegregation of phase occurs, generating an intermediate structure between a monophasic and a biphasic amorphous system.
