Specifically disclosed is a readily degradable resin composition comprising: an aliphatic polyester (A) which has biodegradability; and an aliphatic polyester (B) which has a solution viscosity (η inh) of 0.25 dl/g or less as measured in a mixed solvent composed of m-chlorophenol and 1,2,4-trichlorobenzene at a weight-based ratio of 4:1 at a concentration of 0.4 g/dl and at a temperature of 30° C. and a melt viscosity of 50 Pa S or less as measured at 190° C. at a shear rate of 1 rad/s and is capable of biodegraded at a more rapid degradation rate than the aliphatic polyester (A). Also disclosed is a readily degradable resin composition comprising: an aliphatic polyester (A) which has biodegradability; and an aliphatic polyester (B′) which, when hydrolyzed, can release an acid showing a pH value of 2.0 or less when dissolved in water at a concentration of 0.005 g/ml and is capable of biodegraded at a more rapid degradation rate than the aliphatic polyester (A). Further disclosed is a biodegradable container comprising the readily degradable resin composition.

摘要： An object of the present invention is to provide a method for efficiently producing an oligomer or a monomer by degrading a biodegradable resin using an enzyme, so that the oligomer or the monomer can be recovered.The present invention provides a method for producing an oligomer and/or a monomer by degrading a biodegradable resin in a degradation liquid containing a biodegradation enzyme, a buffer agent, an organic solvent, and water. In this method, the SP value of the organic solvent is less than 8.5 or more than 11.5, and the percentage content of the organic solvent (by volume) in the degradation liquid is higher than 1% and lower than 15%. In the method for producing an oligomer or a monomer, the degradation percentage of the biodegradable resin is low, and deposits of aggregates of the oligomer and/or the monomer are few, so that the recovery percentage is high.
