  An aliphatic polyester improved provided by using water positively as an initiator or/and a molecular weight-adjusting agent, is improved in moisture resistance. More specifically, a cyclic ester containing proton-source compounds including more than 80 ppm of water as an initiator or/and a molecular weight-adjusting agent, is subjected to ring-opening polymerization, and the resultant aliphatic polyester is compounded with a carboxyl group-capping agent to produce such an aliphatic polyester.

  将水作为引发剂或/和分子量调整剂，改进了脂肪族聚酯的防潮性能。更具体地说，将含有质子源化合物的环酯（其中包括作为引发剂或/和分子量调整剂的 80 ppm 以上的水）进行开环聚合，然后将所得脂肪族聚酯与羧基封端剂复合，生产出这种脂肪族聚酯。

  In the production of an aliphatic polyester by ring-opening polymerization of a cyclic ester, at least a latter period of polymerization is proceeded with by way of solid-phase polymerization, and the resultant aliphatic polyester is subjected to removal of residual cyclic ester. As a result, an aliphatic polyester with a minimized content of residual monomer is obtained.

  在通过环酯开环聚合生产脂肪族聚酯的过程中，至少后一段聚合是通过固相聚合的方式进行的，然后将得到的脂肪族聚酯去除残留的环酯。这样就得到了残留单体含量最小的脂肪族聚酯。

  For producing an aliphatic polyester resin composition containing a thermal stabilizer and a carboxyl group-capping agent, the aliphatic polyester resin is first mixed in a hot-melt state with the thermal stabilizer and then mixed in a hot-melt state with the carboxyl group-capping agent. As a result thereof, the resultant aliphatic polyester resin composition is provided with better moisture resistance and noticeably improved heat resistance (less coloring) than in the case where these additives are simultaneously added to effect the hot-melt mixing.

  在生产含有热稳定剂和羧基封端剂的脂肪族聚酯树脂组合物时，首先在热熔状态下将脂肪族聚酯树脂与热稳定剂混合，然后在热熔状态下将脂肪族聚酯树脂与羧基封端剂混合。因此，与同时添加这些添加剂以实现热熔混合的情况相比，所得到的脂肪族聚酯树脂组合物具有更好的防潮性和明显改善的耐热性（着色更少）。

  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.

  一种微粒聚羟基乙酸树脂组合物，包括：第一种微粒聚羟基乙酸树脂和第二种微粒聚羟基乙酸树脂的混合物，每种树脂的含水量不超过 110 ppm，且两者的熔融粘度（在 270°C 和 121 秒-1 的剪切速率下测量，下同）之比高于 1 且不超过 10。聚合后，第一和第二微粒聚乙二醇酸树脂在成型前（如储存期间）或成型过程中可能会导致性能变化。然而，通过充分确定树脂之间的混合比例，同时考虑到其熔融粘度，可以提供一种颗粒状聚乙醇酸树脂组合物，该组合物显示出稳定的熔融成型性，适合作为各种成型工艺的起始材料。
