摘要： A series of renewable bisphenols has been synthesized from creosol (2-methoxy-4-methylphenol) through stoichiometric condensation with short chain aldehydes. Creosol can be readily produced from lignin, potentially allowing for the large scale synthesis of bisphenol A replacements from abundant waste biomass. The renewable bisphenols were isolated in good yield and purity without resorting to solvent intense purification methods. Zinc acetate was shown to be selective catalyst for ortho-coupling of formaldehyde but was unreactive with more sterically demanding aldehydes. Dilute HCl and HBr solutions were shown to be effective catalysts for the selective coupling of aldehydes in the position meta to the phenol. Acid solutions could be recycled and used multiple times without decreases in activity or yield.

摘要： This invention describes resins with phosphate cores and a simple, three-step process for their synthesis. Preferred resins are cyanate ester resins with bridging phosphate groups. These resins can be cured to produce thermoset polymers having Tgs of between 131 and >360° C. depending on the number of cyanate ester groups per phosphate and the substitution pattern of the aromatic rings. The high char yields of these resins, up to about 67%, coupled with the phosphate core means that these materials will have applications as fire-resistant polymers. Additionally, these materials can potentially be blended with conventional cyanate esters or other compatible thermosetting resins to improve the fire resistance of composite materials. Other applications may include use in fire-resistant circuit boards, or as surface coatings to reduce flammability of conventional composite materials or thermoplastics.

摘要： A method to generate dense, multi-cyclic diamondoid fuels from bio-derived sesquiterpenes. This process can be conducted with both heterogeneous and homogenous catalysts and produces the targeted isomers in high yield. The resulting multi-cyclic structures impart significantly higher densities and volumetric net heats of combustion while maintaining low viscosities which allow for use at low temperature/high altitude. Moreover, bio-derived sesquiterpenes can be produced from renewable biomass sources. Use of these fuels will decrease Navy dependence on fossil fuels and will also reduce net carbon emissions.

摘要： A novel family of cycloalkanes compounds having one or more allylidene functionalities which can be used to create cross-linked thermosets and thermoplastics having thermal stability. An example heptacyclo [6.6.0.02,6.03,13.04,11.05,9.010,14] tetradecane (HCTD) complex with terminal allylidene groups at the 7- and 12-positions (HCTD-7,12-diallylidene) was generated from norbornadiene via an efficient six-step synthesis. Thermal polymerization at temperatures ranging from 160 to 240° C. yielded a robust cross-linked material with thermal stability up to 485° C. in air, a glass transition temperature of 377° C., and a char yield (600° C.) of 56% in air. Applications include heat resistant composites utilized in the aerospace, electronic, automotive and textile industries.
