“…Otherwise, only spherical particles are obtained. [70][71][72] In order to know if the formation of higher order morphologies is possible with Table 3, all RAFT polymerizations reached a high overall molar conversion (generally ≥ 89%) within 24 h of reaction. The size exclusion chromatograms in Figure S12 revealed a good blocking efficiency, with molar mass dispersities below 1.6 as long as a DP ≤ 760 was targeted (Table 3).…”

“…9,11,12 While conventional radical polymerization can be used to produce both homopolymers and random copolymers of terpenoid monomers, reversible deactivation radical polymerization (RDRP) techniques are attractive as they allow for both control of molecular weight distributions and also for the productions of more complex macromolecular architectures. To date, both RAFT polymerization 8,9,13,14 and nitroxidemediated polymerization (NMP) 11 of terpenoid (meth)acrylates have been reported. One drawback of these RDRP processes is the relatively long process times needed in order to achieve polymers with good retention of chain end fidelity and narrow molecular weight distributions (6 h for RAFT 8,9 and 8 h for NMP 11 of tetrahydrogeraniol (meth)acrylate).…”

Microwave-Assisted Ultrafast RAFT Miniemulsion Polymerization of Biobased Terpenoid Acrylates

There is a growing preference to move away from traditional petrochemical-based polymers toward biobased alternatives. Here, we report the microwave-assisted RAFT polymerization of several terpenoid acrylates (tetrahydrogeraniol, cyclademol, nopol, and citronellol). These biobased monomers give polymers with a broad range of glass transition temperatures and are excellent candidates to substitute oil-based (meth)acrylates in applications such as coatings and adhesives. First, the process was studied in miniemulsion, finding that all terpenoid acrylates showed a substantial increase in both polymerization rate and reaction control when microwave irradiation was applied. These observations were attributed to nonthermal microwave effects, namely, to changes in the kinetic coefficients under irradiation. The reactions were also carried out in solution, where an amplified nonthermal microwave effect was observed. The results indicate that nonthermal microwave effects allow RAFT polymerization of these terpenoid acrylates to proceed with both improved control and at higher polymerization rates compared to using conventional heating.

“…As well as free radical polymerization, the living radical polymerization of menthyl acrylate and menthyl methacrylate has been heavily explored. 364,435,436,440 Another (meth)acrylate monomer that has been explored is derived from sobrerol, for which different synthetic approaches have been taken (Figure 25). 441,442 Similar to menthol, sobrerol contains a hydroxy functional group and is synthesized through the hydration of α-pinene oxide.…”

Polymers without Petrochemicals: Sustainable Routes to Conventional Monomers

et al. 2022

Access to a wide range of plastic materials has been rationalized by the increased demand from growing populations and the development of high-throughput production systems. Plastic materials at low costs with reliable properties have been utilized in many everyday products. Multibillion-dollar companies are established around these plastic materials, and each polymer takes years to optimize, secure intellectual property, comply with the regulatory bodies such as the Registration, Evaluation, Authorisation and Restriction of Chemicals and the Environmental Protection Agency and develop consumer confidence. Therefore, developing a fully sustainable new plastic material with even a slightly different chemical structure is a costly and long process. Hence, the production of the common plastic materials with exactly the same chemical structures that does not require any new registration processes better reflects the reality of how to address the critical future of sustainable plastics. In this review, we have highlighted the very recent examples on the synthesis of common monomers using chemicals from sustainable feedstocks that can be used as a like-for-like substitute to prepare conventional petrochemical-free thermoplastics.
