method of preparing polyolefin nanocomposite including dispersed carbon support on the polyolefin and nanocomposite prepared thereby

摘要

The present invention relates to a method for producing a polyolefin nanocomposite in which a carbon-based support is dispersed and a nanocomposite produced thereby. More specifically, the present invention relates to: (1) a method in which an organomagnesium compound is added to a surface-Forming a carbon-based carrier; (2) preparing a catalyst for olefin polymerization or copolymerization in which a magnesium-4 transition metal is supported on a carbon-based support by adding a Group 4 transition metal compound to the magnesium-supported carbon-based support and reacting; (3) an organoaluminum compound and 1 to 15Preparing a polyolefin master batch in which the carbon-based support is dispersed by heating at 20 to 100C by adding atmospheric pressure olefin; And (4) preparing a polyolefin nanocomposite in which the carbon-based support is dispersed by mixing the masterbatch and the polyolefin, thereby producing a polyolefin nanocomposite in which the carbon-based support is dispersed .;
