Patent abstract
A process for producing microspheres was developed that provides microspheres with new combined properties of high density, low fracture, high swell capacity, rapid swell, and deformability following swell. The process is reliable and high yielding, and makes use of a low temperature azo initiator and a small molecule chlorinated solvent as the organic phase. The microsphere preparation made using the process is particularly useful in medical treatments such as embolization.
