Defined block copolymers have been made from structurally well defined short diamide blocks, aliphatic di-ester and diols. Rapid crystallization of the copoly(ester-amide)s was observed. Also, a very interesting phase transition was revealed, which was almost independent on cooling rate as well as polymer composition. Optical microscopy and temperature dependent WAXS revealed the co-existence of an isotropic and highly ordered phase in the melt. Biodegradation was shown by soil burial, modified Sturm and BOD tests.
