Abstract:
There is provided a production method in which bis(nitrato)platinum complex, optionally in the concurrent presence of dihalo-platinum complex, and poly(ethylene glycol)-block-poly(glutamic acid) are used at specific ratios and reacted. Coordination compound of an anti-tumor platinum complex with a block copolymer having carboxyl groups on its side chains is efficiently produced.
