PROCESS FOR PREPARATION OF SWELLABLE AND DEGRADABLE MICROSPHERES |
摘要 |
A process for producing microspheres was developed that provides microspheres that are swellable and degradable. The process is reliable and high yielding, and makes use of a low temperature azo initiator, a small molecule chlorinated solvent as the organic phase, and a heat treatment step, and is carried out in absence of a crosslinking agent. The microsphere preparation made using the process is particularly useful as a degradable embolic material. |
