Semi-aromatic polyester; Synthetic polyester


PET (poly(ethylene terephthalate)) is one of the synthetic semi-aromatic polyesters and has terephthalic acid and ethylene glycol units in main chain. PTT (poly(trimethylene terephthalate)) is also a synthetic aromatic polyester with terephthalic acid and propylene glycol units. Both of PET and PTT are thermoplastics and they are used for various applications such as clothes and bottles. Although the term “polyester” is a category of polymers containing the ester linkages in their main chains, most commonly it refers to PET. PET and PTT are prepared by a polycondensation method from the corresponding monomers.


Both of PET and PTT are known as thermoplastics with high mechanical strength, toughness, and fatigue resistance as well as good chemical, hydrolytic, and solvent resistance. They are used for bottles, clothes, packages, sports and recreation goods, household goods, and so on [1, 2, 3, 4]. In this...
