POLYMERIZATION METHOD OF AN AMPHIPHILIC BLOCK COPOLYMER USING AN ORGANOTELLURIUM-MEDIATED LIVING RADICAL POLYMERIZATION, AND A MANUFACTURING METHOD OF A TITANIUM OXIDE NANOSTRUCTURE USING A BLOCK COPOLYMER MICELLE

摘要

PURPOSE: A polymerization method of a block copolymer is provided to synthesize polystyrene-b-poly(2-vinylpyridine) with high yield which is an amphiphilic block copolymer of a low molecular weight with a different block ratio by using a living radical polymerization using an organic tellurium.;CONSTITUTION: A polymerization method of a block copolymer comprises: a step of synthesizing a polystyrene block through a living radical polymerization which uses an organic tellurium as a medium; a step of generating a polymer by accepting 2-vinylpyridine into the polystyrene block; and a step of manufacturing a polystyrene-b-poly(2-vinylpyridine) block copolymer by purifying the polymer through an organic solvent. The molecular weight distribution(Mw/Mn) of the polystyrene-b-poly(2-vinylpyridine) and poly(2-vinylpyridine)-b-polystyrene block copolymer is 1.10-1.24.;COPYRIGHT KIPO 2013
