PROBLEM TO BE SOLVED: To provide a biodegradable injection molded product having excellent impact, heat and hydrolytic resistances and scarcely deteriorating biodegradability essentially possessed by a lactic acid resin. SOLUTION: The biodegradable injection molded product is composed of a resin composition containing the lactic acid resin and an aromatic aliphatic polyester. The mixing ratio of the lactic acid resin to the aromatic aliphatic polyester is within the range of (70:30) to (90:10) expressed in terms of mass ratio. In the resin composition, 5-30 mass% of an inorganic filler may be contained and a carbodiimide compound may further be contained. COPYRIGHT: (C)2004,JPO |
