Title:
ORGANIC ZINC COMPOUND COMPRISING POLYOLEFIN-POLYSTYRENE BLOCK COPOLYMER, AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2016/129818
Kind Code:
A1
Abstract:
The present invention relates to an organic zinc compound comprising a styrene-based polymer or a polyolefin-polystyrene block copolymer at both ends. Also, the present invention relates to a method for preparing the organic zinc compound, the method preparing an intermediate by coordination-polymerizing an olefin monomer using a transition metal catalyst, and then performing anionic polymerization by inserting an alkyllithium compound, an amine ligand, and a styrene-based monomer into the intermediate. Accordingly, the present invention can provide a method for preparing a commercially useful styrene-based polymer or polyolefin-polystyrene block copolymer directly from an olefin monomer and a styrene monomer in a one-pot manner.
