CO-PRECIPITATION METHOD

Methods for preparing a PEG composition by co-precipitation of two or more components to produce a substantially homogenous powder. According to some embodiments, the two or more components are at least and partially soluble in a solvent, and at least one component is a functionalized PEG. Contactin...

Zusammenfassung:	Methods for preparing a PEG composition by co-precipitation of two or more components to produce a substantially homogenous powder. According to some embodiments, the two or more components are at least and partially soluble in a solvent, and at least one component is a functionalized PEG. Contacting the at least two component with the solvent at least partially dissolves the components which are then co-precipitated. The resulting product is substantially homogenous, unlike product made by other methods. The PEG composition may be co-precipitated with additional compounds, such as a colorant like indocyanine green.
