Abstract: The instant disclosure relates to phosphorus-containing compounds that can be used to form flame retardant phosphorus-containing resins, and also can serve as a hardener for a flame retardant epoxy resin compositions. In particular, the phosphorus-containing compounds are modified with acyloxy groups (—O—(C?O)—R), as shown below. Incorporation of the acyloxy groups results in resins that are water resistant and exhibit improved dielectric properties.
Abstract: A series of novel phosphorus-containing compounds having the following formula is provided: in which: R1-R4, A, Q and m are as defined in the specification. A process for the preparation of the compound of formula (I) is also provided. A polymer of formula (PA), and preparation process and use thereof are further provided. A polymer of formula (PI), and preparation process and use thereof are also provided.

Abstract: The subject invention is related to a process for the epoxidation of olefin with peroxide, comprising reacting peroxide with olefin in the presence a solvent, wherein the solvent has Hansen Solubility Parameters (HSPs) of ?T,solvent and ?H,solvent and the epoxide product has Hansen Solubility Parameters (HSPs) of ?T,product and ?H,product, and wherein: ?T,product?6??T,solvent??T,product+6, and ?H,product?6??H,solvent.
Abstract: The subject invention is related to a continuous process of epoxidation of an olefin with supported heteropoly acid catalyst, which does not involve the use of an additive(s). The subject invention separates the products and oxides through a continuous process to reduce backmixing, thereby achieving an efficacy equal to that of a process involving the use of an additive. By excluding additives from the process, the subject invention has a lower cost, and avoids the need for additional wastewater treatment since no alkali metal or alkali earth metal compound is formed during the reaction. Moreover, the continuous process of the invention is also beneficial in industrial manufacturing.

Abstract: A method of reusing micro-encapsulated cholesteric liquid crystals is provided. The method includes providing a display medium material containing a micro-encapsulated cholesteric liquid crystal and a dispersant. The display medium material is mixed with a solvent to form a mixture having a temperature of between 40° C. and 60° C. A centrifugal process is performed to the mixture for separating the micro-encapsulated cholesteric liquid crystal and the dispersant. Then, the dispersant and the solvent are removed to obtain the micro-encapsulated cholesteric liquid crystal.
