Developing thermosets from renewable feedstocks for the production of sustainable polymer networks is of great significance as the world transitions from its heavy reliance on petroleum-derived polymeric materials. Levoglucosan is a renewable chemical, obtained from the pyrolysis of cellulosic biomass and was selected for this study due to its rich functionality. Allyl and pentenoyl levoglucosan monomers were synthesized with selective chemical functionality and were rapidly cured via ultraviolet (UV)-initiated thiol−ene click chemistry to obtain optically transparent, degradable networks. The mechanical properties (tensile strength and Young's modulus) and glass-transition temperature are tunable over the range of 1.08−3.40, 2.50−4.72 MPa, and 3.93−22.8 °C based on the monomer compositions. The resulting thermosets are able to be tailored for desired properties and applications, as demonstrated by stereolithography (SLA) three-dimensional (3D) printing and postcuring modification.

“…The successful large-scale production of LGO and Cyrene by Circa Group Ltd. has led to extensive investigations into their applications. LGO is an important optically pure starting material for the chemical synthesis of pharmaceuticals, , and Cyrene is an environmentally friendly solvent. ,− Recently, the use of LGO and Cyrene in the synthesis of polymeric materials has gained attention. − However, in most reported cases, the bicyclic acetal moiety is not used to construct the polymer main chain.

Unnatural polysaccharide analogs and their biological activities and material properties have attracted considerable research interest. However, these efforts often encounter challenges, especially those related to synthetic complexity and scalability. Here, we report the chemical synthesis of unnatural (1→6)-polysaccharides using levoglucosenone (LGO) and dihydrolevoglucosenone (Cyrene), which are derived from cellulose. Using a versatile monomer synthesis from LGO and Cyrene and cationic ring-opening polymerization, (1→6)-polysaccharides with various tailored substituent patterns are obtained. Additionally, environmentally benign and easy-to-handle organic Brønsted acid catalysts are investigated. This study demonstrates well-controlled first-order polymerization kinetics for the reactive (1S,5R)-6,8-dioxabicyclo[3,2,1]octane (DBO) monomer. The synthesized (1→6)-polysaccharides exhibit high thermal stability and form amorphous solids under ambient conditions, which could be processed into highly transparent self-standing films. Additionally, these polymers exhibit excellent closed-loop chemical recyclability. This study provides an important approach to explore the chemical spaces of unnatural polysaccharides and contributes to the development of sustainable polymer materials from abundant biomass resources.

The present research article delves into the preparation of a new class of bio‐based polyesters from α,ω‐diene furandicarboxylate monomers. In particular, it exploits the use of acyclic diene metathesis polymerisation (ADMET) on 2,5‐furandicarboxylic acid (FDCA)‐derived compounds. First, a library of furan‐based α,ω‐diene monomers was prepared via acid‐ or base‐catalyzed transesterification of 2,5‐furandicarboxylic acid dimethyl ester (FDME) with commercially available alcohols incorporating terminal olefins, i. e., allyl alcohol, but‐3‐en‐1‐ol, hex‐5‐en‐1‐ol and dec‐9‐en‐1‐ol. Then, the novel monomers were subjected to ADMET polymerisation employing different catalysts and reaction conditions. Interestingly, first‐generation Grubbs catalyst was found to be the best promoter for ADMET polymerisation. This catalyst allowed the preparation of a new family of bio‐based polyesters with molecular weights up to 26.4 kDa, with good thermal stability, and adaptable cis‐trans conformations. Results also revealed that the monomer structure had a direct impact on the polymerisation efficiency and the resulting thermal properties. The effect of green bio‐based solvents such as Cyrene™, dimethyl isosorbide (DMI) and γ‐valerolactone (GVL) on the polymerisation process was also studied. Data collected showed that the solvent concentration influenced both the yield and length of polymers formed. Furthermore, some co‐polymerisation experiments were conducted; the successful integration of different monomers in the resulting copolymer was shown to affect the glass transition temperature (Tg) of the resulting materials.
