PURPOSE: A method for manufacturing polyvinylacetate using a static mixer is provided to mix polymerizable materials with excellent mixing ratio, to enable the polymerization of solution using a small amount of a solvent, and to manufacture a polymer having high purity and high molecular weight at low reaction pressure and temperature. CONSTITUTION: A method for manufacturing polyvinylacetate using a static mixture comprises the following steps: preparing a polymerization reaction device including a static mixer reactors(1,2,3,4), a material vessel(21) which is connected to the static mixer reactor, and a heater(19) supplying heat of the reaction; preparing a monomer mixture including vinylacetate, a solvent, and an initiator in the material vessel; supplying the monomer mixture to the static mixer reactor; supplying the heat of the reaction to the static mixture reactor from the heater; and polymerizing the monomer mixture by receiving the heat of the reaction from the heater.
