  • Vinyl chloride-based polymer, method for preparing the same, and thermoplastic resin composition containing the same
    Patent number: 10336847
    Abstract: The present invention relates to a vinyl chloride-based polymer containing an unsaturated fatty acid ester at a specific ratio, a method for preparing the same, a thermoplastic resin composition containing the same, and a thermoplastic resin molded article produced from the composition. The vinyl chloride-based polymer may have good processability, and thus, the thermoplastic resin molded article produced from the thermoplastic resin composition containing the vinyl chloride-based polymer may have high impact strength and improved appearance characteristics.
