Provided is a synthetic resin stent that has resistance to pressure externally applied from the radial direction while in an enlarged diameter state even when the synthetic resin fibers are thin. The synthetic resin stent comprises: a stent main section that is formed by synthetic resin fibers into a cylinder and that can deform from a reduced diameter state to an enlarged diameter state; and a restricting mechanism that keeps the stent main section in the enlarged diameter state by restricting the stent main section from reducing in diameter when in the enlarged diameter state. The synthetic resin stent preferably further comprises a diameter enlarging mechanism that is connected to the stent main section and that deforms the stent main section from a reduced diameter state to an enlarged diameter state.

[PROBLEMS] To provide a material for producing a bioabsorbable material in which it is easy to remove a metal zinc catalyst from a bioabsorbable polymer such as a polymer of lactide or a polymer of lactide and caprolactone and it is easy to recycle the removed powdery metal zinc catalyst, and to provide a bioabsorbable material produced from the material for producing a bioabsorbable material. [MEANS FOR SOLVING PROBLEMS] A material for producing a bioabsorbable material including a three-dimensionally shaped metal zinc polymerization catalyst and a bioabsorbable polymer such as a polymer of lactide or a polymer of lactide and caprolactone; and a process for producing a material for producing a bioabsorbable material, characterized in that in the process for producing a bioabsorbable polymer by polymerization, a three-dimensionally shaped metal zinc catalyst is used as a polymerization catalyst.
