There is a growing preference to move away from traditional petrochem.-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. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Formula: C10H22O).
3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Formula: C10H22O
