Summary Polyanhydrides from cycloaliphatic 1,4-Cyclohexanedicarboxylic acid (1,4-CHDA) were synthesized by melt polycondensation and characterized by WAXD, FTIR and DSC. The results show that these polymer displayed strong crystallinity with highly melting point and can't be dissolved in common solvents. The polymers, which come from different original isomer conformation CHDA, show different melting point and DSC curve. The isomerization happened during the polymerization and reached an equilibrium point at last. By melt polycondensation, the high cis-isomer content polyanhydride is difficult to obtained.
