Abstract Rigid polyurethane (PU) foams were prepared using three North American seed oil starting materials. Polyol with terminal primary hydroxyl groups synthesized from canola by ozonolysis and hydrogenation based technology, commercially available soybean polyol crude castor reacted aromatic diphenylmethane diisocyanate to prepare the foams. Their physical thermal properties studied compared dynamic mechanical analysis thermogravimetric techniques, their cellular structures investigated...
Abstract Polyols synthesized by ozonolysis and hydrogenation from canola oil were reacted with aliphatic 1,6‐hexamethylene diisocyanates (HDI) to produce polyurethane (PU) elastomers. The properties of the materials examined dynamic mechanical analysis (DMA), thermomechanical (TMA), modulated differential scanning calorimetry (MDSC), thermogravimetric (TGA), measurements taken tensile properties. effect dangling chains on network was assessed. formation hydrogen bonds observed FTIR. measured...
Abstract The Avrami model was developed to the kinetics of crystallization and growth a simple metal system. original assumptions do not apply for high‐volume‐fraction crystallizing lipids, although it is incorrectly frequently applied. A modified form model, wellsuited complex lipid kinetics, developed. It produces excellent fits experimental data allows prediction physically meaningful parameters, such as changes in nucleation rate type, rate, morphology, dimensionality. Morphological...
The synthesis of a series ω-hydroxyfatty acid (ω-OHFA) monomers and their methyl ester derivatives (Me-ω-OHFA) from mono-unsaturated fatty acids alcohols via ozonolysis-reduction/cross-metathesis reactions is described. Melt polycondensation the yielded thermoplastic poly(ω-hydroxyfatty acid)s [–(CH2)n–COO–]x with medium (n = 8 12) long 17) repeating monomer units. ω-OHFAs Me-ω-OHFAs were all obtained in good yield (≥80%) purity (≥97%) as established by 1H NMR, Fourier Transform infra-red...
One of the major shortcomings current organic phase change materials (PCMs) is their relatively low melting points, typically below 80°C, which limits integration into thermal energy storage (TES) systems. The present work was aimed at developing lipid-derived PCMs with increased points would be suitable for TES applications requiring higher without compromising other key properties such as enthalpy. introduction an amide group structure linear saturated fatty acids used a means to increase...
