Abstract: Polyesteramides have good mechanical properties and degradability，so using inorganic nanometer materials can
improve the mechanical properties of the polymer. In this paper，PEA/MWNTs were synthesized in-situ using the reinforcement
of nano-composite. We observed the dispersion of multi-walled carbon nanotubes in polyesteramides，and tested the nanocomposite
thermal，mechanical，water absorption and degradation properties of the material. The results show that multi-walled
carbon nanotubes in polyesteramides can be uniformly dispersed，and that the tensile strength and elongation at break increase
and its degradation remains at the same level.

Key words: polymer based composite, carbon nanotubes, degradation, polyesteramides
