Vinyl chloride-vinyl acetate copolymer and method of preparing the same

Abstract

The present invention relates to a vinyl chloride-vinyl acetate copolymer, which may exhibit excellent tensile strength even during low-temperature processing, and a method of preparing the same. The copolymer according to the present invention may exhibit excellent tensile strength even during low-temperature processing by including a vinyl acetate-derived unit in a specific ratio and having a specific range of polydispersity index, for example, a polydispersity index of 2.1 to 2.4, at a degree of polymerization of 1,200 to 1,300. Thus, the vinyl chloride-vinyl acetate copolymer according to the present invention and the method of preparing the same may be easily applied to industries that need them, particularly, automotive industry or polyvinyl chloride resin industry.
