Biodegradable polyester and use thereof
The present invention relates to a biodegradable polyester and use thereof, including components: A) acid components containing following repeating units: 50 to 58 mol % of terephthalic acid A1; 30 to 40 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 present invention, in the case of a high content of the terephthalic acid, the biodegradable polyester prepared by introducing an aliphatic dibasic acid unit having a carbon chain length of 6 or less can satisfy the degradation performance and rigidity and improve the tenacity of the material simultaneously.
