POLYMER, PRODUCTION AND USE THEREOF |
| 摘要 |
<p>The present invention provides a biodegradable high molecular polymer characterized in that the content of water-soluble low molecular compounds, as calculated on the assumption that said compounds each is a monobasic acid, is less than 0.01 mole per 100 grams of said high molecular polymer. The thus-obtained high molecular polymer has good aging stability and can be used advantageously as an excipient for pharmaceutical preparations.</p> |
