Synthesis of vegetable-oil based polymer by terpolymerization of epoxidized soybean oil, propylene oxide and carbon dioxide

Abstract

Although carbon dioxide (CO) is well known as one of the major green-house gases, it is also an economical C1 resource. Thus, CO has been regarded as an appealing starting material for the synthesis of polymers, like polycarbonates by the reaction with epoxides. Herein the reaction between natural epoxidized soybean oil (ESO), propylene oxide (PO) and CO under high pressure (4.0MPa) with the presence of Co-Zn double metal cyanide (Co-Zn DMC) catalyst was studied. Temperature and reaction time were varied accordingly and the products obtained were characterized by FTIR, GPC and H NMR. The results obtained indicate the formation of polycarbonates in the samples collected with yields vary from 60 to 85%. The number average molecular weight (M) of the resultant polymer prepared at reaction temperature of 80°C and reaction time of 6h can reach up to 6498g/mol.

Opportunities for the Use of Brazilian Biomass to Produce Renewable Chemicals and Materials

“…A new monomer with aminosilane pendants was synthesised by Lee and Deng in 2015, by reacting CSO with 3‐aminopropyltriethoxysilane, which could be further reacted with lignin to produce renewable materials [110] . Furthermore, a terpolymerisation with CSO, carbon dioxide and propylene oxide could proceed in a one‐pot synthetic route using a cobalt—zinc catalyst, with a polymerisation yield of 72 % [111] …”

“…[110] Furthermore, a terpolymerisation with CSO, carbon dioxide and propylene oxide could proceed in a one-pot synthetic route using a cobalt-zinc catalyst, with a polymerisation yield of 72 %. [111] Creating photopolymerizable monomers with ESO has been widely explored in the polymeric research field, as it has been discovered that ESO can polymerise via a cationic ring-opening process in the presence of photoinitiators and UV light. [112,113] In 2017, two new monomers were synthesised in a photoinduced click chemistry reaction catalysed by a copper compound.…”

Fabrication and characterization of the ternary composite catalyst system of ZnGA/RET/DMC for the terpolymerization of CO2, propylene oxide and trimellitic anhydride

“…On account of its excellent properties, such as tasteless, odorless, heatproof, hygiene safety, fatigue resistance, insulativity and high impact, polycarbonates exhibit widespread applications in membranes, protective materials, storage medium, electrical appliance industry, building materials industry, packaging eld, and medical devices. 8,9 The synthesis of polycarbonates through the terpolymerizations of CO 2 , epoxides and a third monomer has been achieved using bimetallic complex, rare earth ternary complex and ionic liquid compounds as catalysts under high-pressure conditions. The representative heterogeneous catalyst systems are zinc carboxylate catalyst, bimetallic catalyst, and rare earth composite catalyst, 10 while the typical homogeneous catalyst systems are porphyrin catalyst, binary metal complex, hybrid ligand and metal system.…”

A Rational Investigation of the Lewis Acid-Promoted Coupling of Carbon Dioxide with Cyclohexene Oxide: Towards CO2-Sourced Polycyclohexene Carbonate under Solvent- and Cocatalyst-Free Conditions

“…Although very attractive, this protocol still requires a combination of catalysts and the use of a solvent to reach relatively low molar masses (around 30 kg/mol). In the context of green chemistry, some recent investigations were devoted to the copolymerization and terpolymerisation of CO2 with biobased epoxides precursors [64][65][66]. Scheme 2.…”
