Abstract: Disclosed is a polymer composition including a polyester copolymer and a biodegradable polymer, wherein the polyester copolymer includes two types of ester bond-forming monomer residues as main structural units, when the two types of ester bond-forming monomers are defined as “monomer A” and “monomer B”, respectively, the polyester copolymer satisfies (1) to (3) below, the biodegradable polymer has a melting point of 100° C. or higher, and the biodegradable polymer is included in an amount of 0.1% by weight or more and less than 30% by weight in 100% by weight of the total of the polyester copolymer and the biodegradable polymer. The present invention provides a polymer composition having low Young's modulus and high tensile strength. (1) An R value represented by the following formula is 0.45 or more and 0.99 or less. R=[AB]/(2[A][B])×100, where [A]: molar fraction (%) of monomer A residues in the polyester copolymer, [B]: molar fraction (%) of monomer B residues in the polyester copolymer, and [AB]: molar fraction (%) of a structure in which monomer A residues and monomer B residues are adjacent to each other (A-B and B-A) in the polyester copolymer. (2) A crystallization rate of monomer A residues and a crystallization rate of monomer B residues are less than 14%. (3) A melting point is lower than 100° C. or a clear melting point does not exist.
