Abstract
A polymer production apparatus, including: supplying unit containing first supplying unit to supply raw materials containing monomer, and second supplying unit to supply compressive fluid; contacting unit to bring the monomer and the compressive fluid into contact together; and outlet configured to discharge reaction product of the monomer, wherein reaction unit is provided between the contacting unit and the outlet, where the reaction unit is to pass the monomer from the contacting unit side to the outlet side, while allowing the monomer to carry out a polymerization reaction in the presence of the compressive fluid, and wherein the reaction unit contains circulation unit containing first pipe and second pipe, where a fluid is passed through the first pipe from the contacting unit side to the outlet side, and the second pipe is to return the fluid from return port provided upstream extrusion unit to inlet provided upstream the return port.
