Abstract
A polylactic acid resin composition in which polylactic acid is blended with dibasic acid bis(benzoylhydrazide) represented by general formula (I) below; and a process for producing heat-resistant polylactic acid resin moldings, wherein after the polylactic acid resin composition is melted, the polylactic acid resin composition melted is filled in a die of a molding machine and molded accompanied with crystallization, in which the temperature of the die has been set in a range not higher than the initiation temperature of crystallization and not lower than the glass transition temperature determined with a differential scanning calorimeter (DSC). (In the formula, R represents a alkylene, alkenylene, cycloalkylene, alkylene having an ether bond, or alkylene interrupted with a cycloalkylene, the groups each having 1 to 12 carbon atoms; and R, R, R, and Reach represent a hydrogen atom, halogen atom, alkyl, cycloalkyl, aryl, aralkyl, or alkylaryl, the groups each having 1 to 12 carbon atoms, or Rand Rand/or Rand Rbond to each other to form a five- to eight-membered ring.)
