Abstract
A method for producing a polymer, including: (i) continuously supplying and bringing at least a first monomer, which is ring-opening polymerizable, and a compressive fluid into contact with each other, to thereby allow the first monomer to carry out ring-opening polymerization to continuously generate an intermediate; and (ii) bringing the intermediate and a second monomer, which is identical to or different from the first monomer in kind, into contact with each other, to thereby allow the intermediate and the second monomer to carry out polymerization.
