  • Publication number: 20170145145
    Abstract: The disclosure generally provides high-molecular-weight thermoplastic polyester-based urethanes (TPEUs). In some embodiments, the component monomers of the TPEUs are entirely derived from renewable sources. The disclosure also provides methods of making high-molecular-weight TPEUs, and, in particular, methods for achieving such high molecular weights. The disclosure also provides certain uses of such TPEUs. Entirely lipid-derived segmented thermoplastic TPEU elastomers with rubber-like properties such as low modulus and high elongation were produced by incorporating 1,9-nonanediol (ND) as chain extender with oleic acid derived polyester diols (PEDs) and 1,7-heptamethylene diisocyanate (HPMDI). Enhanced elastomeric properties were achieved by optimizing hydrogen bond density and phase separation of the TPEU via customized polymerization protocols. The novel TPEUs showed extensive degradation under hydrothermal ageing in water at 80° C. and achieved a tensile half-life in one day of immersion.

In some embodiments, the component monomers of the TPEUs are entirely derived from renewable sources. The disclosure also provides methods of making high-molecular-weight TPEUs, and, in particular, methods for achieving such high molecular weights. The disclosure also provides certain uses of such TPEUs. High molecular weight, semi-crystalline TPEU elastomers were synthesized from polyester diols (PEDs) and 1,7 heptamethylene diisocyanate (HPMDI) both derived from oleic acid. Functional group stoichiometry and polymerization time were used as tools to control molecular weight and optimize the thermal and mechanical properties of the TPEU. A targeted range of PEDs with controlled molecular weights and narrow polydispersity indices were obtained in high yields using an induced stoichiometric imbalance method. The PEDs were reacted with HPMDI with different NCO:OH ratios (1.1 to 2.

The disclosure also provides uses of the branched diester compounds in lubricant compositions, for example, as a base oil, and in other applications where their low-temperature and flow properties can be employed beneficially. The disclosure also provides efficient and green methods for making the branched diester compounds. In certain embodiments, a vegetable oil-based diester (1,6-hexyldioleate) was branched with propanoic acid (C3) using a green synthetic approach involving solvent-free and catalyst-free epoxide ring opening followed by in situ normal esterification. A total of three branched ester derivatives possessing varied numbers of internal protruding branched ester groups and hydroxyl groups were obtained. All of the pure branched derivatives were comprised of mixtures of positional isomers and/or stereoisomers.

  • Patent number: 9637698
    Abstract: This application relates to certain dimers as crystallization depressants for biodiesel fuels, and methods for making the same. Such dimers, due to their particular structure and conformation, disrupt the regular packing of linear saturated fatty acid methyl esters, thereby delaying nucleation and mitigating crystal growth. In some embodiments, the dimer includes (E)-1-(1-(oleoyloxy)-3-(stearoyloxy)propan-2-yl) 18-(1-(oleoyloxy)-3-(stearoyloxy)propan-2-yl)octadec-9-enedioate.
