The present disclosure provides a polyester and a molded article. The polyester comprises residues of formula (i), formula (ii), formula (iii) and formula (iv): # imgabs0 # wherein R1 is an aryl group, R2 is a C2-C6 linear hydrocarbon group, and * represents a linking bond. The total of the residues of the formula (ii), the formula (iii) and the formula (iv) is 100 mol%, the residues of the formula (iii) account for 50 mol% to 85 mol%, and the residues of the formula (iv) account for 12 mol% to 40 mol%. The polyester provided by the invention has the advantages of excellent impact strength, high stretchability, high hardness, heat resistance and the like, and does not contain BPA. 本公开提供一种聚酯与一种成形品。聚酯包含式(i)、式(ii)、式(iii)及式(iv)之残基：#imgabs0#其中R1为芳香基，R2为C2-C6直链烃基，*表示连接键。以式(ii)、式(iii)及式(iv)之残基的总和为100mol％计，式(iii)之残基占50mol％至85mol％，而式(iv)之残基占12mol％至40mol％。本公开所提供的聚酯具有优异的冲击强度，同时兼具高拉伸性、高硬度、耐热等优点，并且不含BPA。
