“…Vegetable oil (VO) macromonomers represent advanced polymeric material precursors, an extensive work being devoted to the synthesis of highly functionalized architectures starting from the triglyceride backbones, with unique properties as high reactivity, improved solubility, biodegradability, and so on . However, some properties of VO‐derived polymers remain an unsolved problem due to the long fatty acid chains that cause primarily increased flexibility and thus low T g value or poor mechanical resistance.…”

A series of hybrid systems which combine double‐functionalized linseed oil (methacrylated epoxidized linseed oil) and 2 types of functionalized halloysite (methacrylated halloysite and epoxidized halloysite) was designed in the current study. The curing of the new formulated oil‐clay mixtures was performed via 2 different mechanisms under the influence of the temperature: free‐radical and anionic polymerization. The effect of the functionalized clay tubes against the oil‐based macromonomer reactivity, representing the focus of this study, was monitored by differential scanning calorimetry and Fourier transform infrared spectrometry, concluding that both types of halloysite nanotubes (HNTs) exhibit significant influence on the building of methacrylate/epoxy networks. The effect of the HNTs on the methacrylated epoxidized linseed oil network properties was studied by dynamic mechanical analysis and thermogravimetric analysis, and the morphology of the synthesized hybrids was investigated by scanning electron microscopy. The results suggested that the designed oil‐based hybrid performance is determined by the presence of the both HNT molecules.

“…In response to environmental concerns surrounding petroleum-derived polymeric materials several renewable thermosetting alternatives have been developed. A primary feedstock of these alternatives is vegetable oils (VOs) [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. The functionalization of VOs to prepare thermosetting polymers through free radical polymerization has been developed for several years.…”

The environmental issues of petroleum-derived polymeric foams have necessitated seeking renewable alternatives. This work aims to prepare renewable free-radically polymerized polymeric foams with the ability to biodegrade. Furthermore, this work attempted to incorporate a bio-based reactive diluent, which has not been reported in the literature. The synthesis of maleated castor oil glycerides was performed with products analyzed by Fourier transform infrared spectrometry using attenuated total reflection (ATR-FTIR) and 1H nuclear magnetic resonance (1H NMR) spectroscopy. Polymeric foams were prepared using maleated castor oil glycerides via free radical copolymerization with styrene and isobornyl methacrylate as reactive diluents. Scanning electron microscopy (SEM) was used to determine anisotropic macrocellular morphology, with log-normal cell diameter distributions. The compressive mechanical and energy absorption properties were investigated; the polymeric foams displayed Young’s modulus up to 26.85 ± 1.07 MPa and strength up to 1.11 ± 0.021 MPa using styrene as the reactive diluent, and Young’s modulus up to 1.38 ± 0.055 MPa and strength up to 0.088 MPa when incorporating isobornyl methacrylate. Furthermore, a thorough analysis of the cellular structure–property relationships was performed, indicating relationships to cell diameter, cell wall thickness and apparent density. The polymeric foams displayed rapid mass loss in an aerobic soil environment with multiple erosion sites revealed by SEM. In conclusion, renewable polymeric foams with excellent compressive properties were achieved using styrene as reactive diluent, but the incorporation of isobornyl methacrylate decreased strength-related properties.

Itaconic acid as an effective biobased platform molecule for vat photopolymerisation additive manufacturing

The successful development of renewable feedstocks for monomer and oligomer synthesis has remained limited in its achievable biobased content, and often still rely on toxic compounds for functionalisation (e.g., acrylates). As such, the viability of itaconic acid as an abundant, cheap, and highly sustainable source of functionalisation for free radical polymerisation was explored to overcome these issues. Itaconic acid presented itself as a versatile α,β-unsaturated carbonyl diacid with the ability to be incorporated into monomers via several facile and sustainable synthesis pathways. Owing to these attributes, a novel monomer system composed of an unsaturated polyester oligomer and a castor oil derived monomer were developed and used alongside isobornyl methacrylate as a commercially available biobased reactive diluent for additive manufacturing. This system was demonstrated as an effective combination to achieve tailorable resins for masked stereolithography additive manufacturing with desirable mechanical properties, whilst maintaining a high sustainability.
