While aromatic polyesters such as PET exhibit excellent material properties, they prove to be almost totally resistant to microbial attack.

虽然如PET具有优良的材料性能芳香聚酯，他们几乎完全被证明是抵抗微生物的攻击。

The processability of polyesters could be improved significantly after incorporating stiff chain segment through copolymerization of aliphatic polyester with aromatic liquid crystal element.

在聚酯中引入刚性链段（即将脂肪族聚酯与芳香族、液晶基元共聚合）可改善聚酯的加工性能；
