Synthesis and Structure-Property Relationships of Polyesters Containing Rigid Aromatic Structures
… to enhance thermal and mechanical properties. Copolyesters were prepared through melt polycondensation of diesters and diols in the presence of an exchange catalyst. Monomer incorporation was verified with nuclear magnetic resonance (NMR) and molecular weights were obtained by measuring …

Synthesis and Characterization of Amorphous Cycloaliphatic Copolyesters with Novel Structures and Architectures
A series of random and amorphous copolyesters containing different cycloaliphatic rings within the polymer chains were prepared by melt polycondensaton of difunctional monomers (diesters and diols) in the presence of a catalyst. These polyesters were characterized by nuclear magnetic resonance …
