A biodegradable plastic composition enabling tonstably adjust biodegradation rate, improve hydrolysisnresistance and heat resistance, and retain transparency,nmolded articles thereof and a method for controllingnbiodegradation rate of the biodegradable plastic. In morendetail, a biodegradable plastic composition, characterizednin that said composition is made by compounding 100 partsnby weight of a biodegradable plastic (A), in particular,nan aliphatic type polyester with 0.01 to 5 parts by weightnof a carbodiimide compound (B) and 0.01 to 3 parts by weightnof an antioxidant (C), in particular, a hindered phenol typenantioxidant with a molecular weight of not less than 400nalone or mixed antioxidants of said hindered phenol typenantioxidant and a phosphite type antioxidant, a moldednarticle thereof and a method for controlling biodegradationnrate of the biodegradable plastic. |
