The Thermal Properties and Degradability of Chiral Polyester-Imides Based on Several l/d-Amino Acids.Eight kinds of chiral diacid monomers were prepared with amino acids with different side groups or configurations.  Their thermal properties were analyzed by thermo gravimetric analysis (TGA) and dynamic thermomechanical analysis (DMA), and it was found that the glass transition temperature (Tg) of PEI was mainly affected by the volume of side groups.
