| 摘 要： | 采用PTA路线合成一系列低熔点共聚酯,在不改变其它条件的基础下,通过改变单体的配比,将所获得的聚合物的熔点控制在110℃左右。利用核磁共振对聚合物的序列结构进行表征,发现所制得的聚合物的无规度均接近1,表明所得共聚酯均接近无规共聚物。

| Abstract: | A series of low melting point copolyesters were synthesized by PTA route. The melting point ofthe obtained polymer was controlled at about 110 ℃ by changing the monomer ratio without changing theother conditions. NMR was used to characterize the sequence structure of the polymers. It is found that theprepared polymers all have a randomness close to 1, that indicates the resulting copolyesters are close torandom copolymers. |
