Abstract
A biodegradable polyester and use thereof includes components: A) acid components containing following repeating units: 40 to 48 mol % of terephthalic acid A1; 38.5 to 50 mol % of sebacic acid A2; and 2 to 20 mol % of an aliphatic dibasic acid A3 with a carbon chain length of 6 or less; B) butanediol. In the case of low content of the terephthalic acid unit, by introducing the aliphatic dibasic acid unit with the carbon chain length of 6 or less, mechanical properties of the material can be significantly improved, and the mechanical property retention is better especially when stored in a humid environment.
