Abstract
Provided are a vinyl chloride-based copolymer, as a secondary particle in which primary particles are assembled, which may exhibit excellent mechanical properties and transparency as well as excellent plasticity by having an average pore diameter of 100 nm or less and a porosity of 40 vol % or less, including 65 wt % to 97 wt % of a vinyl chloride-based monomer-derived repeating unit; and 3 wt % to 35 wt % of cis and trans isomers of an unsaturated fatty acid ester-derived repeating units, and including the repeating units respectively derived from the cis and trans isomers of the unsaturated fatty acid ester in a weight ratio of 60:40 to 99:1, and a method of preparing the same.

A vinyl chloride-based copolymer as a secondary particle in which primary particles are assembled,
- wherein the vinyl chloride-based copolymer has an average pore diameter of 100 nm or less and a porosity of 40 vol % or less,
- comprises 65 wt % to 97 wt % of a vinyl chloride monomer-derived repeating unit based on 100 wt % of the vinyl chloride-based copolymer;
- and 3 wt % to 35 wt % of cis and trans isomers of an unsaturated fatty acid ester-derived repeating units based on 100 wt % of the vinyl chloride-based copolymer, and
- comprises the repeating units respectively derived from the cis and trans isomers of the unsaturated fatty acid ester in a weight ratio of 60:40 to 99:1.
