摘要： A particulate polyglycolic acid resin composition, comprising: a blend of a first particulate polyglycolic acid resin and a second particulate polyglycolic acid resin each having a moisture content of at most 110 ppm and providing a ratio of melt-viscosity (as measured at 270° C. and a shear rate of 121 sec−1; the same as hereinafter) therebetween of above 1 and at most 10. After the polymerization, the first and second particulate polyglycolic acid resins can cause change in properties before the forming (e.g., during storage); or during the forming process. However, by adequately determining the blending ratio between the resins while taking the melt-viscosities thereof into account, it becomes possible to provide a particulate polyglycolic acid resin composition showing a stable melt-formability and suitable as a starting material for various forming processes.

摘要： Ring-opening polymerization of a cyclic ester is performed by using an alcohol and water positively as initiators or/and molecular weight-adjusting agents to control the initial properties and properties with time of the resultant aliphatic polyester. More specifically, an aliphatic polyester is produced by ring-opening polymerization of a cyclic ester containing water and an alcohol based on a total proton concentration and a ratio between a mol concentration of carboxyl (carboxylic acid)-source compounds including water and a mol concentration of alkoxycarbonyl (ester)-source compounds, as polymerization-controlling indexes.
