Abstract
Disclosed are a vinyl chloride based nanocomposite composition and a method of preparing the vinyl chloride based nanocomposite. According to the present invention, a method of preparing a straight vinyl chloride based nanocomposite having a nanomaterial uniformly dispersed therein, by using the vinyl chloride based nanocomposite composition when a vinyl chloride monomer is suspension polymerized in the presence of a protective colloidal agent and a polymerization initiator after preparing a water dispersion suspension using the vinyl chloride based nanocomposite composition based on a hydrophilic composition is provided.
Claims6
A method of preparing a vinyl chloride based nanocomposite, the method comprising:
- mixing a hydrophilic inorganic nanomaterial, at least one hydrophilic polymer selected from an unsaturated organic acid based polymer and a polycarboxylic acid based (co)polymer, and water to prepare a water dispersion suspension;
- adding a protective colloidal agent and a vinyl chloride based monomer to the water dispersion suspension and mixing to prepare a solution;
- adding an initiator to the solution and suspension polymerizing to prepare a slurry of the vinyl chloride based nanocomposite;
- adding reaction terminators when reaction pressure in the suspension polymerization reaches 6.0 to 8.0 kg/cm2;
- and
- drying the slurry of the vinyl chloride based nanocomposite in a fluidized bed dryer to prepare the vinyl chloride based nanocomposite.
