Title:
CLAY-SUPPORTED NICKEL DIIMINE CATALYST AND METHOD FOR PREPARING POLYOLEFIN/CLAY NANOCOMPOSITE USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/155753
Kind Code:
A2
Abstract:
The present invention provides a clay metal composite obtained by modifying an organic metal compound, using clay including an organic reforming agent a clay-supported nickel diimine catalyst including a nickel diimine catalyst that is supported by the clay metal compound, a method for preparing same, a polyolefin/clay nanocomposite using the clay-supported nickel diimine catalyst, and a method for preparing same. The clay-supported nickel diimine-based catalyst of the present invention contain metal components in the organic metal compound which significantly improves polymerization catalytic activity and provides a polyolefin/clay nanocomposite having superior dispersion of the clay in the polyolefin by effectively stripping the layered composition of the clay, which is enabled by the metal components being coupled to the clay, thus accelerating the in-situ polymerization of an olefin monomer.
