Abstract

This application relates to microporous, open-celled polymeric foam materials with physical characteristics that make them suitable for a variety of uses produced from high internal phase emulsions (HIPEs). This application particularly relates to oxidatively stable emulsifiers used to stabilize the HIPE and the foams produced from such HIPEs.
