| abstract | (57) [Summary] [Constitution] The present invention is useful as a polymer for bioabsorbable pharmaceutical preparations, has a weight average molecular weight of about 5,000 or more and 30,000 or less, contains no catalyst, and is a dispersion obtained by gel permeation chromatography. About 50-95% by weight of lactic acid with a degree of about 1.5-2 And a lactic acid / glycolic acid copolymer comprising about 50 to 5% by weight of glycolic acid. [Effect] Since the copolymer of the present invention undergoes polycondensation without using any polymerization catalyst, the obtained copolymer does not contain any polymerization catalyst, and thus can be mainly used as a pharmaceutical preparation base. For example, steroid hormones, peptide hormones, or carcinostatic agents, etc. are contained, and they can be advantageously used as implantable or microcapsule sustained-release preparations, or fine particles containing carcinostatic agents are prepared and embolization therapeutic agents. |
