摘要:Provided in the present invention is polyester synthesis based on aspartic acid modification. A monomer of a unique structure of an imide ring is obtained based on aspartic acid and a dibasic acid likely to be cyclized, the monomer is based on the aspartic acid, can be derived from biomass, is low in cost and renewable, meets the requirement of sustainable development, and the unique structure of the monomer can regulate and control various properties of polyester materials, such as the mechanics, temperature resistance, hydrophilicity and hydrophobicity, and crystallization.
