    摘要： A catalyst and a method for preparing S-indoxacarb using the catalyst. The catalyst is prepared using 3-tert-butyl-5-(chloromethyl)salicylaldehyde and cyclohexanediamine as raw materials, where an original quinine catalyst such as cinchonine is replaced with the catalyst for application in the asymmetric synthesis of tert-butyl hydroperoxide and 5-chloro-2-methoxycarbonyl-1-indanone ester, greatly improving selection in the asymmetric synthesis process, with the S-enantiomer content increasing from 75% to over 98%, achieving the recycling of a high-efficiency chiral catalyst, and greatly reducing production costs. The synthesis process of the catalyst is simple and is favorable for industrialization, and lays good foundations for the production of high-quality indoxacarb.

    摘要： The present invention generally relates to covalent network polymers prepared from an imine-linked oligomer and an independent crosslinker comprising reactive moieties selected from the group consisting of epoxy, isocyanate, bismaleimide, sulfide, polyurethane, anhydride, polyester and combinations thereof. The covalent network polymers disclosed herein are advantageously made by anhydrous reactions, which enables the highest known glass transition temperatures to date for this class of materials. Further, the disclosed covalent network polymers can be formed in continuous processes, such as additive manufacturing processes that produce three-dimensional objects or roll-to-roll processes that produce covalent network polymer films or fully cured prepreg in various size formats.

    摘要： Formaldehyde-free binder compositions are described that include an aldehyde or ketone, a nitrogen-containing salt of an inorganic acid, and an acidic compound. The acidic compound may be an organic acid, such as maleic acid or citric acid among others. The acidic compound is supplied in quantities that lower the pH of the binder composition to about 5 or less. The binder compositions may be used in methods of binding fiberglass and the resulting fiberglass products have an improved tensile strength due to the addition of the acidic compound.
