    • The present technology relates generally to the production of HMF-glycerin acetal, ethers, diethers, esters, and diesters derived therefrom, and aliphatic or aromatic polyester polymers derived therefrom. For example, HMF-glycerin acetal of the present technology can be formed as a product of the condensation reaction of glycerin with HMF. Compounds produced in accordance with the present technology may have many desirable attributes. For example, the incorporation of rigid furan and dioxolane five membered rings in the backbone of both polyurethanes and polyesters should result in polymers with high Tg and, hence, high service temperatures. Such polymers are also believed to be sensitive to bio- and photo-degradation.
    • 本技术一般涉及由其衍生的HMF-甘油缩醛,醚,二醚,酯和二酯的制备,以及衍生自其的脂族或芳族聚酯聚合物。 例如,本技术的HMF-甘油缩醛可以形成为甘油与HMF的缩合反应的产物。 根据本技术生产的化合物可具有许多期望的特性。 例如,在聚氨酯和聚酯的主链中加入刚性呋喃和二氧戊环五元环应该导致具有高Tg,因此具有高使用温度的聚合物。 这些聚合物也被认为对生物和光降解敏感。

    • A composition and method for enhancing the thermal conductivity in heat transfer systems. The composition comprises a powder having average particle sizes in the nanometer to micron size range, a coating for corrosion resistance and/or acting as a dispersant, and a heat transfer medium. The heat transfer medium is selected from the group of interpolymers, polymers, gaseous and liquid fluids and phase change materials. Suitable powders include metals and metal oxides, alloys or blends thereof, and carbon derivatives. The surface of the powder is modified by surface complexes or physical adsorption with a coating compound. The coated powder, when mixed with a heat transfer medium, forms a colloidal dispersion which exhibits enhanced heat transfer capacity and thermal conductivity, stable chemical composition, faster heat transfer rates, and dispersion maintenance which are beneficial to most heat transfer systems.
    • 一种提高传热系统导热性的组合物和方法。 该组合物包含具有纳米至微米尺寸范围内的平均粒度的粉末,用于耐腐蚀和/或用作分散剂的涂层,以及传热介质。 传热介质选自互聚物,聚合物,气态和液体流体以及相变材料。 合适的粉末包括金属和金属氧化物,它们的合金或共混物以及碳衍生物。 粉末的表面通过表面复合物或用涂料化合物物理吸附而改性。 涂覆的粉末当与传热介质混合时形成胶体分散体,其表现出增强的传热能力和导热性,稳定的化学组成,更快的传热速率和分散维持,这对大多数传热系统是有利的。
