Covalent incorporation of the surfactant into high internal phase emulsion templated polymeric foams†
Abstract
High internal phase emulsions of water in cyclooctene stabilised by sorbitan monooleate (Span 80) were cured by ring-opening metathesis polymerisation to release fully open macroporous polymer foams wherein the surfactant was covalently incorporated into the poly(cyclooctene) strands via chain transfer reactions.
