Rapid copolymerization of canola oil derived epoxide monomers with anhydrides and carbon dioxide (CO2)

摘要: A canola oil derived monomer, 1-decene, was converted to 1,2-epoxydecane with >90% yield. The ring opening copolymerization of carbon dioxide (CO2) and different cyclic anhydrides including maleic, succinic, itaconic, phthalic tetrahydrophthalic carried out using a double metal cyanide (DMC) catalyst under microwave conventional heating conditions. microwave-assisted polymerizations were significantly faster than those observed polycarbonates, copolymers CO2, synthesized within minutes (∼30 min) conditions high conversions (up 99%), carbonate linkage (∼88%) molecular weight (Mw ∼ 15 kDa). polyesters, anhydrides, in ∼60 min ester content 90%) Mw 17 characterized by Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (1H NMR), gel permeation chromatography (GPC), differential scanning calorimetry (DSC) thermal gravimetric analysis (TGA) techniques. configuration bonds unsaturated polyesters such as poly(1-decene-co-maleate) completely isomerized through post polymerization modification enhance its activity an polyester resin (UPR) for potential applications.
