“…It is possible to obtain biobased epoxy resins with different approaches. In the last years, many investigations have been developed and characterized in the field of epoxy resins from vegetable oils such as epoxidized linseed oil (ELO) [13][14][15][16][17], modified soybean oil [15,16,[18][19][20][21][22][23][24] and other less known oils such as those derived from microalgal oil [25], jatropha oil [26], 407 Properties of biobased epoxy resins from epoxidized linseed oil (ELO) crosslinked with a mixture of cyclic anhydride and maleinized linseed oil M.

This works aims at the development thermosetting resins derived from epoxidized linseed oil (ELO) of high biobased content, by using a mixture of crosslinking agents, i.e. methyl nadic anhydride (MNA) and maleinized linseed oil (MLO). By using only MNA as crosslinking agent, the obtained resins are characterized by high stiffness and, consequently, high fragility. When MLO content increasing in the crosslinking mixture, up to 25 wt%, a decrease in mechanical resistant and thermomechanical is detected, thus indicating that MLO can provide flexibility to ELO-based thermosetting resins which is an interesting issue to obtain tailored properties by selecting the appropriate mixture composition. In general, the thermosetting resin crosslinked with 10 wt% MLO and 40 wt% MNA gives balanced properties together with noticeable biobased content, thus broadening the potential of these materials for uses in green composites and coatings.

“…Camelina oil is also used in cosmetic and pharmaceutical industries, among others, to manufacture creams and lotions. It is also used in the chemical industry; since now, there were few studies on the use of camelina oil for biodiesel production [9,11,[13][14][15].…”

The camelina oil, registered in EU as Traditional Speciality Guaranteed, is an excellent edible oil rich in x3 fatty acids, as well as a great raw material for biodiesel production. However, both variable seed quality and technological difficulties (cold pressing, no chemical refining procedure) exert an unfavorable impact on a final oil quality and its oxidative stability. Therefore, oxidative stability parameter seems to be a significant distinguishing feature of camelina oil. The aim of this work was to compare the oxidative stability of selected camelina oils and assessment of kinetic parameters of their oxidation determined by PDSC and the Rancimat methods. Coldpressed camelina oils were initially characterized by basic quality parameters: fatty acids composition, free fatty acids, peroxide value and anisidine value. The isothermal PDSC and Rancimat procedures were conducted within the temperature range of 90-130 and 80-120°C, respectively. From the obtained results, the times to reach the oxidation peak maximum (s max ) obtained from PDSC analysis were compared with induction times (s on ) determined by Rancimat test. Based on the Arrhenius equation and transition state theory, activation energies (E a ), pre-exponential factors (Z) and specific rate constants (k) of oils oxidation at selected temperatures were calculated. Strong correlation between PDSC and Rancimat methods (R 2 [ 0.98) using a polynomial equation was obtained; thus, PDSC method can be preliminary recommended as an appropriate objective method for assessing the oxidative stability of camelina oils. To the best of our knowledge, this is the first study on the possible use of PDSC technique to analyze the kinetics of oxidation of camelina oil.

Photocross linking of the resins composed of plant‐derived monomers, acrylated epoxidized soybean oil (AESO), myrcene (MYR) and vanillin dimethacrylate (VDM) or divinylbenzene (DVB, for comparison), was performed using 2,2‐dimethoxy‐2‐phenylacetophenone as photoinitiator. Photocross‐linking rate and properties of the crosslinked polymers depended on the resin compositions. The higher amount of MYR caused not only the better homogenization and lower viscosity of the resin but also the reduction of polymerization rate and the worse mechanical and thermal properties of the resulting polymers. The higher amount of aromatic component (VDM or DVB) improved mechanical and thermal properties of polymers. Moreover, the use of VDM instead of DVB in the system led to the higher photocross‐linking rate and higher yield of insoluble fraction. The resin composed of only plant‐derived monomers AESO/MYR/VDM, molar ratio 1:1:3, showed characteristics comparable to those of commercial petroleum‐derived photoresins and was selected as a potential renewable photoresin for application in optical 3D printing. © 2019 Wiley Periodicals, Inc.
