Title:
鎖末端官能性化したポリエチレンオキシド及びこれを用いたナノ寸法の遷移金属及びその塩の製造方法
Document Type and Number:
Japanese Patent JP2009500488
Kind Code:
A
Abstract:
There is provided a novel chain-end functionalized PEO of formulas (I) to (IV) prepared via living anionic polymerization and chain-end functionalization, as well as a simple method of preparing nano-sized transition metal or metal salt particles using the same, which can be readily stabilized even in an aqueous medium. The water-soluble PEO-based polymers having various functional groups (including a drug group such as vitamin and anti-cancer agent) and the process of preparing nano-sized transition metal or metal salt particles using the same can be advantageously used in the development of new materials for drug delivering system and imaging, e.g., a contrast agent and an anti-cancer agent simultaneously.
