Patent AT-E399535-T1: [Translated] METHOD FOR PRODUCING MICROPARTICLES WITH A SELECTED POLYMER MOLECULAR WEIGHT

Published by National Center for Biotechnology Information (NCBI) | U.S. Department of Health & Human Services | Catalog Last Checked: September 07, 2025 at 01:08 PM | Dataset Last Updated: September 06, 2025
The present invention provides a method for preparing microparticles having a selected polymer molecular weight. The hold time and temperature of a solution containing a nucleophilic compound and a polymer having a starting molecular weight are controlled in order to control the molecular weight of the polymer in the finished microparticle product. In this manner, a selected polymer molecular weight in the finished microparticle product can be achieved from a variety of starting material molecular weights.
