Abstract
The present disclosure relates to a process for preparing porous crosslinked hydrophilic polymeric materials. Such materials can be prepared from oil-in-water high internal phase emulsions (HIPEs) containing hydrophilic polymers. The oil-in-water high internal phase emulsion (HIPE) comprises two phases: an external continuous aqueous phase containing at least one hydrophilic polymer; and an internal oil phase. The hydrophilic polymer is crosslinked to form a three-dimensionally crosslinked polymer matrix. The internal oil phase is subsequently removed to obtain a porous crosslinked hydrophilic polymeric material. The present invention also relates to porous crosslinked hydrophilic polymeric materials prepared by such a process.
