摘要:
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 each of said compounds 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.
The thus-obtained high molecular polymer has good aging stability and can be used advantageously as an excipient for pharmaceutical preparations.
