    摘要: An aliphatic polyester resin composition is provided which is excellent in heat resistance, moldability and hydrolysis resistance. The aliphatic polyester resin composition comprises a biodegradable polyester resin (A) essentially including an α- and/or β-hydroxycarboxylic acid unit and crosslinked by at least one crosslinking agent (B) selected from the group consisting of (meth)acrylate compounds and polyvalent isocyanate compounds, wherein some or all of carboxyl groups of the resin (A) are blocked by 0.01 to 20 parts by mass of a terminal blocking agent (C) based on 100 parts by mass of the resin (A).
