High temperature properties of poly(styreneco-alkylmaleimide) foams prepared by high internal phase emulsion polymerization

PolyHIPE: IPNs, hybrids, nanoscale porosity, silica monoliths and ICP-based sensors

“…PolyHIPE, with their porous structure, have demonstrated advantageous structural properties and absorbency for use as absorbents [6][7][8][9][10]. PolyHIPE have also been used in ion exchange systems [11,12] and as heat resistant structural foams [13][14][15][16]. PolyHIPE can be synthesized from a wide variety of monomers and have a wide range of potential applications.…”

“…Several high temperature polyHIPE have been investigated: the copolymerization of N-substituted maleimide and bismaleimide [14][15][16] and the copolymerization of a maleimide-terminated aryl ether sulfone macromonomer using a non-aqueous HIPE [24]. Polysilsesquioxanes (SSQ) have attracted much attention for their extraordinary heat and fire resistance [25].…”

Preparation of macrocellular PU–PS interpenetrating networks

“…The monomer system the most commonly used corresponds to the copolymerisation of styrene (Sty) with divinylbenzene (DVB) [8,16], leading to very rigid and relatively brittle materials (PS). Therefore, in order to improve the properties of the materials, other formulations have been considered [2,[16][17][18][19].…”

Effect of rubber on microcellular structures from high internal phase emulsion polymerization

“…A number of applications include polymeric membranes, ion exchange resin, 3,4 controlled release systems, absorbents and inertial confinement fusion targets. 5,6 The success in these applications strongly depends on the microcellular structure having large surface area, i.e., small cell size. Over the years, many researchers have investigated the effects of polymerization conditions, such as sorbitan monooleate as a surfactant, divinylbenzene as a crosslinking agent, dodecane as a pore size controller, and the introduction of inorganic materials, on the cell sizes and properties of the foam.…”
