1·The producing process of phosphorus series inflaming retarding copolyesters with copolymerizing method was introduced, and the properties of products were studied.
介绍了共聚法磷系阻燃共聚酯的生产过程，并对产品性能进行了研究。
2·Progress on biodegradable aliphatic-aromatic copolyesters based on aliphatic and aromatic diacids, diols and ester monomers was reviewed.
综述了以脂肪族酯和芳香族酯为单体制备生物可降解脂肪族-芳香族共聚酯的研究进展。
3·The Lnk1 and T(?) of copolyester with 10% m-benzene dicarbonic acid were smallest, and it's mechanical properties were also best in all studied copolyesters.
均下降，同时，力学性能也下降，但间苯二甲酸含量为10％的共聚酯的力学性能最佳。
4·It was found that all copolyesters are thermotropic nematic liquid crystals with wide mesomorphic temperature range.
结果发现各共聚酯均为向列型热致液晶，并都具有较宽的液晶态温度范围。
