A kinetic study of the acceleration effect of substituted benzyl alcohols on the cationic photopolymerization rate of epoxidized natural oils

Utilization of green seed canola oil for in situ epoxidation

“…The preparation of plastic materials based on natural plant oils has become one of the most promising topics in materials science. The triglycerides that constitute plant oils can be transformed into polymerizable monomers by several chemical modifications such as epoxidation, acrylation of epoxies, metathesis of double bonds, or transesterification [2]. Thus, the versatility of the triglycerides has attracted the interest of many scientists around the world [3].…”

Thermal properties, curing characteristics and water absorption of soybean oil-based thermoset

“…Jin and Park [7] proposed thermally induced ring opening polymerization route for ESO thermoset initiated by N-benzylquinoxalinium hexafluoroantimonate thermal latent initiator. Ortiz et al [9] reported that radical induced cationic photopolymerization of ESO thermoset in the presence of diarylinodonium salt photo-initiator follows conventional cationic polymerization mechanism and chain reaction mechanism. Gao [10] proposed that the curing mechanism of catalytic ESO-anhydride thermosets involves reaction of the tertiary amine with ESO monomer followed by the ring opening of the anhydride functional group with the alkoxide.…”

Photopolymerization Reactions: On the Way to a Green and Sustainable Chemistry

“…Renewable monomers/oligomers have been proposed and studied; e.g., (i) acrylates: acrylated vegetable oils [118], natural or naturally derived products (photocrosslinkable polylactides [119], ε-caprolactone [120,121], poly (lactide-co-ethylene oxide-co-fumarate) [122], poly(caprolactone-colactic acid) [123], methacrylate based gelatine derivatives [124], acrylate modified starch [125] and itaconic acid based photocurable polyesters [126]; (ii) epoxides: epoxidized sunflower [127,128], epoxidized soybean oil (ESO), linseed oil, vernonia oil or castor oil (see in [129]), limonene dioxide (LDO) [130] (limonene is a liquid terpene found in various volatile oils, such as cardamom, nutmeg and turpentine; LDO can be formed through oxidation of limonene by peracids), epoxidized natural rubbers [131], vegetable oils [132] and epoxidized fatty acid (EFA); or (iii) resins based on vegetable oil [133,134], soybean [135], rosin ester [136], tung [137] and palm stearin [138,139] and castor oil. The photopolymerization of such monomers is more or less efficient as a function of the chemical structure, the multifunctional character or the irradiation conditions.…”
