Title:
METHOD FOR PREPARING VINYL CHLORIDE-BASED COPOLYMER AND VINYL CHLORIDE-BASED COPOLYMER PREPARED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2016/195434
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a vinyl chloride-based copolymer exhibiting excellent plasticity and processability, a vinyl chloride-based copolymer prepared therefrom, a thermoplastic resin composition containing the vinyl chloride-based copolymer, and a thermoplastic molded product manufactured therefrom. The preparation method, according to the present invention, can improve copolymerizability with a vinyl chloride-based monomer by continuously injecting or split-injecting, during a certain polymerization conversion rate period, an unsaturated fatty acid ester mixture used as a comonomer, and can decrease unreacted unsaturated fatty acid ester mixture, and consequently, markedly improve the degree of conversion of the vinyl chloride-based copolymer. Thus, the vinyl chloride-based copolymer prepared from the preparation method can exhibit markedly improved plasticity and processability.
