“…The Green Polyols presented OH values between 83 and 119 mg KOH g (Table ) and very low acid values, except for B1‐Green Polyol which displayed a relatively high acid value due to its longer epoxidation reaction time. Although the OH values achieved using the green route are relatively lower compared to those of the PMTAG Polyols prepared previously with solvents, they are large enough to make suitable monomers for the preparation of flexible as well as rigid foams. B3‐ and B4‐ Green Polyols which displayed very low acid values, no formic acid attached and significantly different OH values (83 and 119 mg KOH g −1 , respectively) were chosen for further physical characterizations, and used for the preparation of rigid and flexible polyurethane foams.…”

Green Polyols were synthesized from a 1-butene cross metathesized palm oil (PMTAG) using a green, solvent free epoxidation and hydroxylation pathway. The synthetic strategy was adapted to control the degree of double bond epoxidation and ultimately the hydroxyl value of the polyols. The polyols comprised diol and tetrol monomers with terminal hydroxyl groups content as high as 18 mol %, and achieved hydroxyl values between 83 and 119 mg KOH g 21 . Functional Rigid and highly flexible foams were prepared from two designer Green Polyols. The foams presented a high thermal stability (T on of degradation of 270 8C), suitable glass transition temperatures (212 8C and 50 8C) and compressive strength (0.21 MPa at 10% strain and 1 MPa at 10% strain for the flexible and rigid foams, respectively) which are superior to existing lipid-based counterparts.

Olefin cross metathesis of natural oils and fats is an important organic synthesis technique that is used to produce fine chemicals, substrates, and materials, many of which serve as or are potential petrochemical replacements. [16][17][18][19][20] The cross metathesis reaction effectively shortens some of the unsaturated fatty acids of the TAGs at the unsaturated sites, producing terminal double Additional Supporting Information may be found in the online version of this article.

“…7 Vegetable oils are the potential alternatives due to the abundance, relatively low cost and its renewability. 8,9 Palm kernel oil (PKO) is obtained from the kernel part of the oil palm fruit and is considered palm oil waste. Due to its abundance in Malaysia, the researchers are encouraged to produce value-added products from PKO such as polyester in polyurethane (PU) industry.…”

Palm Kernel Oil Polyol-based Polyurethane as Shape Memory Material: Effect of Polyol Molar Ratio

Shape memory polyurethane (SMPU) has found application in a variety of field such as textile, sensors, structural and food industry due to its unique and composition dependent properties. However, most SMPU are synthesised using petroleum-based raw materials. This has triggered the effort in finding an alternative source of raw materials due to the environmental awareness. For this purpose, SMPU was synthesised based on palm kernel oil polyol (PKO-p) up to 40% molar ratio in replace of petroleum-based polyol, polycaprolactone diol (PCL). SMPU was synthesised via two-step bulk polymerisation process incorporated with PKO-p, PCL as the switching segment, 4,4-methylene-bis (cyclohexyl isocyanate) and 1,4-butanediol. The SMPU were characterised by Fouriertransform infrared (FTIR) spectrometer, differential scanning calorimetry (DSC), tensile and shape memory test. The incorporation of PKO-p has enhanced the shape memory behaviour and tensile properties. The degree of soft segment crystallinity increased with the addition of PKO-p, hence improved its ability to fix the temporary shape upon cooling. Besides, the shape recovery remains 100% even at 40% of PKO-p suggesting the presence of sufficient amount of physical crosslinking to hold the permanent shape. On the other hand, SMPU at 10% molar ratio of PKO-p showed high tensile strength and elongation at break.

“…It is due to the fact that electrical conductivity is highly correlated to the phospholipids and metals concentration in oil. Pillai et al (2016) had described structure, chemical composition and physical properties of metathesized palm oil and novel polyol derivatives. Physical characteristics of spray-dried dairy powders containing different vegetable oils (sunflower oil, palm oil and its mixtures) were studied by Kelly et al (2014).…”
