| titleOfInvention | Block copolymer with reduced impurity content, polymer carrier, polymer pharmaceutical preparation, and method for producing the same |
| abstract | A purification method useful for producing a polymer carrier having a purity capable of sufficiently removing impurities in a block copolymer of a polyethylene glycol and a polyacidic amino acid and also being usable in pharmaceutical preparations and the like. Disclosed are a method for producing a polymer carrier, a block copolymer having a reduced impurity content, the polymer carrier, and a polymer drug preparation using the polymer carrier. Also disclosed is a method of quantifying polyethylene glycols and polyacid amino acids as impurities contained in the block copolymer using an ion exchange resin or a partition adsorption resin and then using a gel filtration column. |
