Abstract

The present invention provides an aliphatic polyester, a polyester composition containing the same, and use thereof. The aliphatic polyester includes a dicarboxylic acid residue and a diol residue; the dicarboxylic acid residue includes the following residues: a1) based on a total molar percentage content of a1) and a2) as 100 mol%, 61.2-69 mol% of a succinic acid residue; and a2) based on the total molar percentage content of a1) and a2) as 100 mol%, 31-38.8 mol% of a sebacic acid residue; and the diol residue is selected from a 1,4-butanediol residue with a molar content at least equal to that of the dicarboxylic acid residue. In the present invention, the aliphatic polyester has good uniformity in terms of transverse and longitudinal tear resistance, high tensile strength, and a short biological disintegration period under home composting conditions, thereby meeting home composting requirements.
