“…PPG is generally hydrophilic but becomes water‐insoluble when its molecular weight is higher than 740 g mol −1[ 63 ] Also, Myr is a hydrophobic acyclic monoterpene which can be another reason for high GC values in water for the synthesized NIPUs. [ 64 ] High GC values of samples are an indication of the high resistance of cured NIPUs in moist environments. The nature of the diamine and the backbone material used to synthesize the NIPUs obviously play a role in dictating the final properties of the cured material.…”

Hybrid non‐isocyanate poly(urethanes) (HNIPUs) are designed from a precursor whose carbonate functionality is derived from epoxy‐functional statistical copolymers. Specifically, a bio‐based diene (β‐myrcene) is copolymerized via conventional free radical polymerization with glycidyl methacrylate (GMA) at different molar ratios, producing flexible copolymers with epoxy pendant groups, which are then reacted with carbon dioxide to yield the precursors with cyclic carbonate functionality. Subsequent addition of an amine‐terminated telechelic poly(propylene glycol) (PPG) forms urethane linkages in the side chains, whose concentration is tuned by varying the GMA initial molar fraction. The NIPUs are end‐capped with silanes to enable moisture curing, resulting in HNIPUs with elongations at break up to 150%, and relatively low elastic moduli varying from 32 kPa to 50 kPa as the number of urethane side linkages increases from 6 to 22. The swelling ratio of the NIPUs is also measured in tetrahydrofuran (THF). As the number of urethane side chains increases, the swelling ratio of the NIPUs decreases (710% to 620%), indicating a higher crosslinking density. All samples have gel contents higher than 50% in THF, indicating non‐crosslinked species in the hybrid samples which confirms the relatively low reported tensile moduli.

“…The BET specific surface area of the PLE monolith was determined as 20.47 m 2 g -1 as given in Table 1. This result indicated that by incorporating d-limonene into polyHIPE network, the specific BET area value of the obtained monoliths slightly increased due to the increment in cross-linking ratio of monoliths when compared with monoliths synthesized by using 100% EGDMA [17].…”

“…Synthesized HIPEs were transferred into glass jars and the HIPEs were kept in an air-circulated oven at 60°C for 24 h. Subsequent to polymerization, the resulting monoliths were extracted with ethanol in a Soxhlet apparatus for 24 h to achieve typical polyHIPE morphology. The samples were air-dried at 40 o C until the weight kept constant [17].…”

“…By polymerization of the external monomer phase and removal of the internal phase by extraction process, highly cross-linked, open porous, and low density monoliths which termed as polyHIPE, can be synthesized for specific applications such as catalysis, energy storage and tissue engineering [14][15][16]. The first time in the literature, Mert and Kekevi [17] achieved to synthesize porous terpene based monoliths by free radical polymerization of βmyrcene with ethylene glycol dimetacrylate (EGDMA) by using emulsion templating process and showed that in the presence of β-myrcene, monoliths has gained elasticity.…”

Colloidal templating is a versatile and practical method to prepare macroporous polymer monoliths with a welldefined two-stage porosity and tuneable morphology. Due to their advantageous morphology colloidal templated monoliths can find application in many areas. In this study, a renewable monomer was used for the development of sustainable macroporous polymer monoliths. Copolymerization of a renewable monomer mixture in a colloidal system was achieved by using a flexible diacrylate crosslinker. For this purpose, d-limonene was copolymerized with ethylene glycol dimetacrylate (EGDMA) in equivalent ratios to investigate the effect of monomer structure on the final material properties. In the end, thermal and morphological properties of the resulting sustainable macroporous polymer monoliths were investigated by Differential Scanning Calorimetry (DSC), Thermal Gravimetric Analysis (TGA) and Scanning Electron Microscopy (SEM), respectively. Additionally, the specific surface area of the obtained monolithic materials was measured through N 2 adsorption/desorption analyses by applying Brunauer-Emmet-Teller (BET) equation to the N 2 isotherms of the samples. It was determined that the presence of d-limonene led to an extraordinary one-hollowed ring morphology due to the porogen effect of this renewable monomer.

“…Mert's group polymerised myrcene with various comonomers, namely ethylene glycol dimethacrylate (EGDMA), 1,3-butanedioldiacrylate (BDDA), divinylbenzene (DVB) and 4-vinylbenzyl chloride (VBC) to produce various polyHIPEs. 22,23 Additionally, the polyHIPEs based on myrcene were hypercrosslinked to increase their specific surface area from 2.25 m 2 g −1 to 60.18 m 2 g −1 , 23 modified with nanoclay to improve their mechanical properties and interconnectivity 24 and used for the adsorption of different organic solvents. 25 In this study limonene, carvone and myrcene will be used to synthesise bio-based polyHIPEs by using either trimethylolpropane triacrylate (TMPTA) or pentaerythritol tetraacrylate (PETA) as the crosslinkers.…”
