Abstract
The present disclosure is directed to a class of fluorinated copolymers, such as PTFE copolymers, that can be dissolved in low toxicity solvents, such as Class III Solvents, and that enable the creation of stable water-in-solvent emulsions comprising the fluorinated copolymers dissolved in a low toxicity solvents and a hydrophilic agent (e.g., a therapeutic agent) dissolved in an aqueous solvent, such as water or saline.
