Abstract

Provided is a vinyl chloride-containing copolymer having both improved impact resistance and improved tensile yield strength. The vinyl chloride-containing copolymer according to the present invention is produced by copolymerizing 30 to 98 wt% inclusive of an acrylic copolymer with 2 to 70 wt% inclusive of a vinyl chloride monomer, wherein the acrylic copolymer is produced by copolymerizing 100 parts by weight of an alkyl (meth)acrylate monomer with 0.1 to 10 parts by weight inclusive of a polyfunctional monomer. The vinyl chloride-containing copolymer according to the present invention has a volume average particle diameter of 0.1 to 500 [mu]m inclusive.

Description

technical field [0001] The present invention relates to a vinyl chloride-based copolymer capable of improving both impact resistance and tensile yield strength. In addition, the present invention relates to a vinyl chloride-based resin composition and a molded article using the above-mentioned vinyl chloride-based copolymer. Background technique [0002] Vinyl chloride-based resins are generally excellent in mechanical strength, weather resistance, and chemical resistance. Therefore, vinyl chloride resins are processed into various molded products and used in many fields. However, vinyl chloride-based resins have a problem of relatively low impact resistance when used in rigid applications. Therefore, studies are underway to improve the impact resistance of vinyl chloride-based resins. [0003] As an example of a vinyl chloride-based resin having improved impact resistance, the following Patent Document 1 discloses a vinyl chloride-based resin obtained by graft-copolymeri...
