Novel elastic rubbers from CO₂-based polycarbonates

Abstract

We report the fixation of carbon dioxide (CO2) into novel rubber polymers based on polycarbonate domains. Our strategy consisted in the atom-efficient terpolymerisation of CO2 with long-alkyl-chain epoxides and unsaturated...

“…For instance, we can find polymers as fluorescent, flexible materials in the textile industry, for 3D printers, as well as coatings/varnishes/paints, and adhesives. 1–7…”

Access to Functionalized Polycarbonates Derived from Fatty Acid Esters via Catalytic ROCOP and Their Potential in Gel Formulations

“…33 More recently, other groups have also utilized this "Kleij" catalyst in the realm of (fatty) PC/hybrid polymer synthesis, further showing its generic value as a privileged system. 34,35 We envisioned that a similar strategy would be beneficial for the ROCOP of fatty acid epoxides and CO 2 (Scheme 1c) affording conformationally flexible PCs with a controllable degree of functionality by virtue of preselected ester functions in the fatty acid monomer or by choosing a mixed renewable monomer feed.…”

“…Our group has been long interested in the use of renewable terpene-derived epoxides toward the formation of tailor-made, functionalized PCs, polyesters, and polyurethanes via catalytic ROCOP. ,− Key to the success of these processes has been the use of either Al- or Fe-centered aminotriphenolate complexes as modular complexes for the activation of often sterically demanding terpene epoxides (Scheme b) . More recently, other groups have also utilized this “Kleij” catalyst in the realm of (fatty) PC/hybrid polymer synthesis, further showing its generic value as a privileged system. , We envisioned that a similar strategy would be beneficial for the ROCOP of fatty acid epoxides and CO 2 (Scheme c) affording conformationally flexible PCs with a controllable degree of functionality by virtue of preselected ester functions in the fatty acid monomer or by choosing a mixed renewable monomer feed.…”

CO2-Based Polycarbonates with Low Glass Transition Temperatures Sourced from Long-Chain Terpenes

“…In recent years, there has been a focus on polycarbonate-based TPEs, leading to the development of novel materials that combine polycarbonates with polymers such as polyesters. , Polyesters frequently serve as the soft block in these TPEs due to the scarcity of polycarbonates capable of achieving both low glass transition temperatures and high molar masses, two crucial parameters for superior TPE performance. Fossil fuel-based polycarbonates such as poly­(1,2-hex-5-ene carbonate) with a T g of −22 °C or 1,2-epoxydecane with T g of −39 °C and castor oil-based polycarbonate with a T g of −44 °C, have been reported in literature. Our research group recently introduced citronellol-based polycarbonates with a T g of −54 °C.…”
