Polyamide is a class of widely used polymer material,which usually has outstanding thermal stability and mechanical durability,but also has the problem of slow degradation rate.Polyesters have good degradability and hydrolysis ability,but slightly inferior mechanical properties.The recently emerging polyesteramide is an advanced material formed by the copolymerization of ester and amide segments.It combines the advantages of polyamide and polyester and is expected to be applied in the fields of drug delivery and degradable plastics.Discussions and summaries are conducted around the main raw materials for synthesizing polyesteramide,conventional methods for preparing polyesteramide,and the advantages and disadvantages of different methods are summarized.
