PROBLEM TO BE SOLVED: To provide a method for manufacturing a polymer by polymerizing monomers having a vinyl bond at high productivity, where the polymer has polymerization percentage of 60% or more which was difficult to discharge stably as high viscosity and is high molecular weight polymer.SOLUTION: There is provided a manufacturing method of a polymer by melting or dissolving monomers having a vinyl bond by contacting the monomer having the vinyl bond and compressive fluid with a mixing ratio satisfying a relationship of the following formula (1) by using a polymerization reaction machine, thereafter addition-polymerizing the monomers having the vinyl bond in a presence of an initiator and discharging the resulting polymer from the polymerization reaction machine. 0.5≤mass of raw material/(mass of raw material+mass of compressive fluid)≤0.9 (1)SELECTED DRAWING: None |
