Abstract:
1. A biodegradable resin composition for molding comprising: 100 parts by weight of a biodegradable polyester resin comprising not smaller than 50% by weight of polylactic acid having a melting point of not lower than 160° C., the biodegradable polyester resin having a melt flow rate of 0.1 to 50 g/10 mm as measured under a load of 21.2 N at 190° C.; 0.1 to 20 parts by weight of a phyllosilicate containing a primary, secondary or tertiary amine salt, a quaternary ammonium salt or a phosphonium salt ionically bonded between layers thereof; and 0.01 to 10 parts by weight of at least one compound selected from the group consisting of a polyalkylene oxide, an aliphatic polyester, a polyalcohol ester and a polycarboxylic acid ester, based on 100 parts by weight of the biodegradable polyester resin, the compound having a boiling point of not lower than 250° C. and a number-average molecular weight of 200 to 50,000.
