A series of polymerized high internal phase emulsion (polyHIPE) materials have been prepared by using a water in oil emulsion stabilized by a macro-RAFT agent, 2-(butylthiocarbonothioylthio)-2-poly(styrene)-b-poly(acrylic acid), acting as a polymeric surfactant.

ABSTRACTRecently we reported on a method of preparing microcellular composite foams. In this procedure an open-celled polystyrene foam is prepared by the polymerization of a high-internal-phase water-in-oil emulsion containing styrene, divinylbenzene, surfactant, free-radical initiator and water. After drying, the cells of the polystyrene foam are then filled with other materials such as aerogel or resoles. The physical properties of these materials e.g., surface area, density, thermal conductivity, and compressive strength will be presented.

Functional micelles with a poly(N-isopropylacrylamide) (PNIPAM) shell and a cross-linked poly((acrylic acid)-co-(ethylene glycol diacrylate)) core have been successfully prepared in one pot by the reversible addition–fragmentation chain transfer (RAFT) copolymerization of acrylic acid and ethylene glycol diacrylate in selective solvent using PNIPAM-SC(S)Ph as a RAFT agent. Since PNIPAM and poly(acrylic acid) are temperature- and pH-sensitive polymers, respectively, the micelles obtained should display double environmental sensitivity to temperature and pH in water.
