“…Polyesters have been used as a major binder since the starting of the 19th century because of their excellent auto‐oxidative, chemical, and mechanical properties . The general methods for preparing polyesters are (1) the polycondensation reaction of hydroxyl group (OH) containing organic acids or diacids with a diol and (2) the ring‐opening polymerization of lactones (Scheme ) .…”

“…6 Polymeric properties depend on the reactivity of vegetable oils, the properties of fatty acids, and their relative percentages. 6 For example, the dielectric properties of oleic acid based PU was assessed by Velayutham et al, 7 and they found that the proton originating from the oleic acid determined the relaxation mechanism of the dielectric properties of PU. The authors claimed that the higher oleic acid content produced a higher amount of flexible side changes, and this resulted in a less compact polymer.…”

The utilization of renewable resources for the preparation of new materials is an alternative option for reducing the high demand of fossil feedstocks. Vegetable oils are potential bioresources that are renewable and abundantly available. Triglyceride-based vegetable oils, such as soybean, jatropha, linseed, sunflower, palm, castor, nahar seed, and canola oil, are being considered as precursors in the production of polymers. In this article, we attempt to summarize advancements in processes and technologies for the synthesis of polymers from various kinds of vegetable oils. The advantages and disadvantages of these biobased polymers with respect to traditional monomer-based ones are also highlighted.

“…The problem of insufficient unsaturation could be overcome through the incorporation of maleic anhydride or fumaric acid into the alkyd structures, to make them UV-curable [16,17]. Further exploration of palm oil derivatives has produced many new coating resins that have various film properties [18,19,20,21]. In 2014, a US patent was granted for a palm oil-based polyurethane oligomer for use as a restorative dental material [22].…”

UV-Curable Urethane Acrylate Resin from Palm Fatty Acid Distillate

Palm fatty acid distillate (PFAD), is a by-product of the crude palm oil refining process. It comprises mainly of free fatty acids—around 45% palmitic and 33% oleic acids—as the major components. Ultra-violet (UV) curable urethane acrylate (UA) oligomers could be synthesized from PFAD, by the following procedure. A hydroxyl terminated macromer was first prepared by reacting PFAD with a mixture of isophthalic acid, phthalic anhydride, neopentagylcol (NPG), and pentaerythritol. The macromer was then reacted with 2-hydroxylethylacrylate (2HEA) and toluene diisocynate (TDI) to generate a resin, containing acrylate side chains for UV curable application. A series of UA resins were prepared by using 15, 25, 45, 55, and 70% of PFAD, respectively. The UA resin has Mw in the range of 3,200 to 27,000. They could be cured by UV irradiation at an intensity of 225 mW/cm2. Glass transition temperature (Tg) of the cured film was measured by differential scanning calorimeter (DSC), and hardness of the film was determined by a pendulum hardness tester, according to American Society for Testing and Materials (ASTM)4366. The resins were used in a wood-coating application. All of the cured films showed good adhesion, hardness, and chemical resistance except for the one using the 70% PFAD, which did not cure properly.

All of the cured films showed good adhesion, hardness and chemical resistant for resins using up to 55% PFAD; however the resin at 70% did not cure properly. oil at USD200 -250 per metric tonne for usage in animal feed [28,29]. There was no report of its application in coating. This project has aimed to synthesize PFAD urethane acrylate with different PFAD content. The urethane acrylates (UA) were investigated as UV curable resins for wood coating applications.
