METHOD OF MANUFACTURING SOLID DISPERSION

摘要

A simple and convenient method of manufacturing a solid dispersion, which eliminates drawbacks in the conventional method, by the use of a twin-screw extruder. This invention enables simple and easy manufacture of a solid dispersion without heating chemicals polymeric carriers to temperatures higher than respective melting points thereof and also without using any organic solvent for dissolving both the chemicals. The solid dispersion thus manufactured exhibits high functional characteristics.
