A radical polymerization method that enables synthesis, at a high conversion rate, of polymers having a relatively uniform molecular weight and is applicable to various monomers, and an apparatus used for the method. A reaction solution containing monomer and initiator is continuously or intermittently circulated in the apparatus and is heated in a heating-initiation unit to a predetermined temperature simultaneously across a radial direction of a cross section of the flow path whereby the initiator located in a particular volume of the reaction solution is cleaved all at once. The apparatus includes a heating medium production unit 10, a heating medium-reaction solution mixing unit 20, a cooling unit 30, and a recovery unit 40 for a reaction mixture, all communicatively connected by the flow path and optionally a heating reaction unit 60, a cooling unit 70, and a recovery unit 80, all communicatively connected by the flow path.
A method of producing a polymer by causing a reaction solution containing a monomer and a radical polymerization initiator to continuously or intermittently flow through a flow path of a radical polymerization reaction apparatus, the method comprising:
