Several stable non‐aqueous apolar‐in‐polar medium internal phase emulsions (MIPEs) containing divinyl adipate and pentaerythritol in the continuous phase are formulated by varying the nature of the hydrocarbon. Polycondensation is then conducted either under conventional heating or microwave irradiation after addition of a commercially available organocatalyst. Solvent elimination and drying lead to the corresponding polyester polyMIPEs. A tremendous morphological difference between materials is observed according to the heating method employed. The particular efficiency of microwave activation in the polycondensation of the continuous phase of a non‐aqueous emulsion is discussed.

“…Polymerization chemistries are being developed to take advantage of monomers from renewable resources and macromolecular structural chemistries are being developed to enhance degradability. PHs that were based on renewable resource monomers such as polyphenols (e. g., tannin, tannic acid, lignin), plant oils (e. g., soybean, castor), polysaccharides (e. g., alginate, chitosan, dextrin, pectin), and lactide have recently been developed, [62,[115][116][117][118][119][120] as were PHs that were based on polymers containing degradable groups (e. g., esters). [57][58][59][60]62,[121][122][123][124][125][126][127][128][129] In addition, the recent advent of reactive surfactants and/or reactive nanoparticles for HIPE stabilization has produced a significant reduction in the amounts of leachable components.…”

Porous polymers have been evolving continuously since the introduction of foam rubber in 1929. Today, pore diameters ranging from sub‐nanometre to millimetre can be generated controllably. Cutting‐edge porous polymers are now being applied at the forefront of critical problems with societal and environmental impact including advanced systems for biomedicine, water purification, energy storage, and gas purification and storage. The commonly‐used pore generation approaches include macromolecular design, self‐assembly, phase separation, solid and liquid templating, sol‐gel formation, and foaming. In each, The Chemistry of Polymers, both the polymerization chemistry and the macromolecular structural chemistry, must be applied advantageously to generate the empty volume within the polymer and then fix it in place. This essay will traverse the various pore size scales, describing the chemistries involved and discussing their implications.

“…Due to the black liquor has high lignin content, it stands as a promising phenolic source (FOULET et al, 2016;GOSSELINK et al, 2004;NASEEM et al, 2016). Besides lignin, tannin has a high flavonoid content, which holds a polyhydroxyphenol units associations, being another renewable polyphenolic alternative (BOTHA et al, 1978;JANA et al, 2015;PIZZI, 2003).…”
