A process for dissolving modified cellulose is disclosed. The process includes contacting modified cellulose with a solvent in a mixture to form swelled modified cellulose and then contacting the mixture with a salt to dissolve the swelled modified cellulose.

Dissolution of oxidized cellulose

A process for dissolving modified cellulose includes contacting modified cellulose solution with at least one multivalent cation to form a plurality of modified cellulose particles.

Dissolution of oxidized cellulose and particle preparation by cross-linking with multivalent cations

A process for dissolving modified cellulose includes contacting modified cellulose with a solvent in a mixture to form swelled modified cellulose and then contacting the mixture with a salt to dissolve the swelled modified cellulose. The dissolved modified cellulose is used to form at least one of a predictably degrading coating, film, or a fiber.

Medical devices based on oxidized cellulose

A process for forming microspheres is disclosed. The process includes contacting a solvent with a modified cellulose to form a solution; contacting the modified cellulose solution with at least one bioactive agent to form a discontinuous phase liquid; contacting the discontinuous phase liquid with a continuous phase liquid to form an emulsion; and contacting the emulsion with a third phase liquid to extract the solvent from the emulsion, thereby forming a plurality of modified cellulose microspheres.

Oxidized cellulose microspheres

A process for dissolving modified cellulose includes contacting modified cellulose solution with at least one neutralizing agent to form a plurality of modified cellulose particles.

Dissolution of oxidized cellulose and particle preparation by dispersion and neutralization

A process for dissolving modified cellulose includes contacting modified cellulose solution with at least one non-solvent to form a plurality of modified cellulose particles.

Dissolution of oxidized cellulose and particle preparation by solvent and non-solvent precipitation

Crosslinked polymers, methods for their preparation and use, are described in which the crosslinked polymers are formed from at least two polymer precursors, one of which is designed, upon degradation of the crosslinked polymer, to release the second polymer precursor in its original, unmodified chemical form.
