ALIPHATIC POLYESTER RESIN COMPOSITION, ALIPHATIC POLYESTER RESIN MOLDING AND PROCESS FOR PRODUCING THE ALIPHATIC POLYESTER RESIN MOLDING

摘要

Molded articles with improved physical characteristics are obtained under molding conditions for general resin without causing deformation at the mold releasing time if a composition containing aliphatic polyester resin and one or more metal salts of aromatic sulfonate of a specified kind is used. Such a composition is placed inside a mold maintained at a temperature below the crystallization-initiating temperature by differential scanning calorimetry and above the glass transition temperature is molded while it crystallizes.
