Abstract

The present invention relates to a method for preparing a vinyl based polymer and a vinyl based copolymer including a vinyl chloride based material through suspension polymerization in which the generation of foam is prevented while maintaining the pressure by slowly increasing the reaction temperature when the pressure starts to drop at a reaction terminal stage. In the method for preparing a vinyl based resin a vinyl chloride based monomer is suspension polymerized to reduce the generation of foam and improve the quality of protrusions thermal stability and the like.
