Synthesis and characterization of cast resin based on different saturation epoxidized soybean oil

Abstract

Acrylated epoxidized soybean oils (AESOs) with different level of saturation were obtained by the ring opening of different saturation epoxidized soybean oils using acrylic acid as the ring opener. AESO-based thermosets have been synthesized by free radical polymerization of these AESOs and methyl methacrylate. The thermal properties of these resins were studied by differential scanning calorimetry and thermo-gravimetric analysis. The results indicated that the thermal stability of these resins depends upon the epoxy value; the glass transition temperature increases with increasing of epoxy value. The tensile and impact strength of the resins were also studied, and indicated that tensile strength increases with increasing epoxy value, whereas impact strength decreases. The resulting thermosets ranged from elastomers to glassy polymers.

Hydroaminomethylation of oleochemicals: A comprehensive overview

“…Countless functionalizations of oleochemicals have already been implemented [5]. The carbon-carbon double bonds of fatty acids, fatty esters, and triglycerides have especially been converted into epoxy [6][7][8][9][10][11][12][13], hydroxyl [14][15][16][17][18][19][20][21], formyl [22][23][24][25][26][27], acrylate [28][29][30], or crossmetathesis derivatives [31][32][33], to name only a few. The functionalization of the carbon-carbon double bonds by amino groups is also of great interest.…”

“…Amino vegetable oils are mainly being synthesized through epoxy ring‐opening of epoxidized oils . However, as the ring‐opening reaction does not proceed readily with internal epoxide, high reaction temperatures, and catalysts are often required . Another approach to obtain amino vegetable oils consists in a four‐steps procedure where the CC double bonds are first converted into polyhydroxy oils which then undergo oxidization to yield polyketones.…”

Properties of Biobased Epoxy Resins from Epoxidized Soybean Oil (ESBO) Cured with Maleic Anhydride (MA)

“…Due to the recent shift on green or ecological issues that have taken place in society in general, research on naturally-based, thermoset polymers is taking on an ever increasing importance as these materials can be used to substitute the traditional thermo-stable petrochemical polymers, which are difficult to recycle. For this reason, there is a great deal of current research work on epoxidized vegetable oils, such as linseed oil, soybean oil, rape seed oil, castor oil and sunflower oil as a base for ecological, thermoset polymers [1][2][3][4][5].…”

Effects of different epoxidation methods of soybean oil on the characteristics of acrylated epoxidized soybean oil-co-poly(methyl methacrylate) copolymer

“…Acrylation of epoxidized vegetable oils is one of the interesting techniques for preparing the vegetable oil-based polymers. The mechanical and thermal properties of acrylated epoxidized soybean oil (AESO) have been reported [3,5,8,20,23,38,39]. It has been established that AESO shows higher mechanical properties than ESO [22,39].…”

“…It has been established that AESO shows higher mechanical properties than ESO [22,39]. AESO has been used for copolymerization with other materials such as a vinyl ester resin containing styrene [8][9][10] and with poly(methyl methacrylate) [38][39][40]. It was found that the mechanical properties of an AESO-co-PMMA copolymer were higher than those of AESO.…”
