Effect of polyHIPE porosity on its hydrodynamic properties
Polymer Testing, 2021 Several polymerized high internal phase emulsions (polyHIPE) of various porosity but the same pore diameter were prepared. It was demonstrated that the pore size distribution of void pores and interconnecting pores is similar and it can be described by a

Supporting ruthenium initiator on PolyHIPE
Journal of Molecular Catalysis A, 2006 Abstract PolyHIPE samples were successfully synthesised using divinylbenzene and styrene as polymerisable continuous phase, aqueous phase containing potassium persulphate and calcium chloride dihydrate, a mixture of emulsifiers (SPAN20, CTAB and DDBSS) and toluene as a porogen.

Reusable Pd-PolyHIPE for Suzuki–Miyaura Coupling
ACS Omega, 2022 Palladium was immobilized on a highly porous copolymer of 4-vinylpyridine and divinylbenzene (polyHIPE-poly(high internal phase emulsion)) using palladium(II) acetate to obtain PolyPy-Pd with 6.1 wt % or 0.57 mmol Pd/g. The immobilized catalyst was able to catalyze the coupling of iodobenzene and phenylboronic acid in ethylene glycol monomethyl ether ...

Flow-Through PolyHIPE Silver-Based Catalytic Reactor [PDF]
Polymers, 2021 Catalytic reactors performing continuously are an important step towards more efficient and controllable processes compared to the batch operation mode. For this purpose, homogenous high internal phase emulsion polymer materials with an immobilized silver catalyst were prepared and used as a continuous plug flow reactor.
