“…4a-c. In the 1 H-NMR spectrum of epoxy ester resin, the peaks at 0.9, 1.2, 1.3 and 1.5 ppm are characteristics for CH 3 and CH 2 groups present in the fatty acid moiety in epoxy ester resin. The peaks at 2.7 and 5 ppm correspond to the protons of oxirane ring and hydroxyl group of epoxy ester resin respectively.…”

“…Depletion of fossil fuels used in the paint formulations and their high cost along with serious environmental hazards forces industries to search for cheaper, eco-friendly and renewable resources like plant resins and vegetable oils. Vegetable oil based waterborne (WB) resins generally use water as solvent [3,4]. They are non-toxic, nonflammable, odourless and eco friendly in nature due to their low VOC contents.…”

“…Plant oils are great candidates for toughening thermosetting resins because of their biodegradability, renewability, and availability . Meanwhile, soybean oil, a highly consuming edible oil, has attracted the most attention in industrial uses including its epoxidized form used as a reactive diluent for epoxy resins to overcome the aforementioned brittleness.…”

Two kinds of bio-resourced reactive diluents have been synthesized from linseed oil.The prepared epoxidized linseed oil (ELO) and the cyclocarbonated linseed oil (CLO) were separately blended with a petroleum-based tetra-functional epoxy resin (TGDDM) to improve its processability and to overcome the brittleness of the thermoset network therefrom. The linseed oil modifications were spectrally established, and processability improvement of the resin blends was rheologically confirmed. The curing of samples was studied by differential scanning calorimetry, and their mechanical properties (ie, tensile, flexural, fracture toughness, and adhesion) were investigated as well. Scanning electron microscopy images were obtained to reconfirm the toughness improvement of the modified thermosets. In contrast of the epoxidized soybean oil (ie, the most conventionally studied bio-based reactive diluent), ELO and CLO had no negative effects on the thermoset material characteristics. They improved properties such as tensile strength (up to 43.2 MPa), fracture toughness (1.1 MPa m 1/2 ), and peel-adhesion strength (4.5 N/25 mm). It was concluded that ELO and CLO were efficient reactive diluents to be used in formulations of polymer composites, surface coatings, and structural adhesives based on epoxy resins.

“…The hybrid polymers obtained by miniemulsion polymerization with incorporation of plant oils are also formed by these grafting mechanisms. The substitution of an alkyd resin by a plant oil has been already proposed in the production of crosslinkable coatings . Some plant oils have similar curing capabilities as alkyd resins because of a similar double bond content, but they have a significantly lower molecular weight.…”

Miniemulsion polymerization reactions of methyl methacrylate were conducted in the presence of plant oils, in order to investigate the effect of different types (linseed oil and andiroba oil) and amounts of oils on the polymerization reaction rates and on the molecular weight of the produced polymers. A decrease in the reaction rate, that was proportional to the number of double bonds present in the triglycerides, was observed. Polymers with lower molecular weights were obtained when triglycerides with higher number of double bonds were used. The experimental data were analyzed with a mathematical model developed to represent the kinetics of these reactions, including the kinetic mechanisms associated to free radical miniemulsion polymerization with an oil-soluble initiator, and the model was able to predict the variation in the polymerization reaction rate depending on the type and amount of the plant oil
