Abstract: A polyester resin composition having excellent hydrolysis resistance and excellent transparency and a method of producing the same are provided. There is provided a polyester resin composition comprising a polyester resin that is obtained from a dicarboxylic acid or an ester-forming derivative thereof and a diol as main raw material; and a copper-containing compound and a nitrogen-containing compound having a nitrogen-containing heterocyclic structure or a tertiary amine structure that are mixed with the polyester resin.

Abstract: There is provided a polylactic acid resin composition, comprising 0.15 to 0.90 parts by weight of an organic nucleating agent (B) in addition to 100 parts by weight of a polylactic acid resin (A) comprised of a poly-L-lactic acid component and a poly-D-lactic acid component. The polylactic acid resin composition satisfies the following (i) to (v): (i) amount of a linear oligomer of L-lactic acid and/or D-lactic acid is equal to or less than 0.3 parts by weight (ii) rate of weight-average molecular weight retention is equal to or greater than 70% after the polylactic acid resin composition is retained in a closed state at 220°C for 30 minutes; (iii) degree of stereocomplexation (Sc) exceeds 80%; (vi) stereocomplex crystal melting heat quantity ”Hmsc is equal to or greater than 30 J/g; and (v) cooling crystallization heat quantity (”Hc) is equal to or greater than 20 J/g.
