| titleOfInvention | Method for preparing polyvinylchloride |
| abstract | The present invention relates to a method for producing a polyvinyl alcohol copolymer, comprising the steps of: a first polymerization step in which a polymerization reaction is carried out while the vinyl chloride monomer is first charged and heated to a first polymerization temperature in the presence of an initiator; And a second polymerization step of polymerizing the organic peroxide-based material and the vinyl chloride-based monomer at a first polymerization temperature for 20 to 60 minutes, followed by a polymerization reaction, wherein the organic peroxide-based material is a polymerization initiator And the half life at the first polymerization temperature is not more than 40 minutes. |
