Abstract:
The synthesis of certain polyester diols (PEDs) is disclosed. This application also discloses the purification and polymerization kinetics of lipid based PEDs. Molecular weight and distribution controls were achieved by initial and induced stoichiometric imbalance and optimization of the purification protocol. Thermal degradation and thermal transition behavior of the PEDs were also investigated by TGA and DSC.
Abstract:
This invention relates to base ester compounds and complex ester compounds that can be used as a base stock for lubricant applications or a base stock blend component for use in a finished lubricant or for particular applications, and methods of making the same. The base ester compounds and complex esters described herein comprise dimer and/or trimer esters, and their respective branched derivatives.
Abstract:
The synthesis of semi-crystalline thermoplastic polyester urethanes is disclosed. The synthesis describes parameters such as controlled concentration, distribution, and types of crystalline hard segment blocks to correlate the effect of hard segment crystallinity to that of the soft segment blocks.
Abstract:
Metathesized triacylglycerol green polyols and their related physical and thermal properties are disclosed. Such metathesized triacylglycerol green polyols are also used as a component of polyurethane applications, including polyurethane foams.
Abstract:
Metathesized triacylglycerol polyols derived from certain natural oils, including canola oil, and their related physical properties are disclosed. Such metathesized triacylglycerol polyols are also used as a component of polyurethane applications, including polyurethane foams.
Abstract:
This application relates to the polymorphism and microstructure of certain triacylglycerols and fatty acid methyl esters, and how the properties of these individual components in a biodiesel fuel, as well as their combined mixtures, helps understand the fundamental mechanisms of their crystallization so as to design biodiesel fuels with improved low temperature characteristics.
