A method for producing a polymer, including: (i) bringing a compressive fluid and raw materials containing a ring-opening polymerizable monomer into contact with each other at a mixing ratio represented by the following formula, to thereby allow the ring-opening polymerizable monomer to carry out ring-opening polymerization in the presence of a metal catalyst: 1{Mass of the raw materials/(Mass of the raw materials+Mass of the compressive fluid)}0.5. |
