  • Patent number: 10669360
    Abstract: Various embodiments provide dye-doped polystyrene microspheres generated using dispersion polymerization. Polystyrene microspheres may be doped with fluorescent dyes, such as xanthene derivatives including Kiton Red 620 (KR620), using dispersion polymerization. Certain functionalities, such as sodium styrene sulfonate, may be used to shift the equilibrium distribution of dye molecules to favor incorporation of the dye into the particles. Polyelectrolyte materials, such as poly(diallyldimethyl ammnonium chloride), PolyDADMAC, may be used to electrostatically trap and bind dye molecules within the particles. A buffer may be used to stabilize the pH change of the solution during dye-doped polystyrene microsphere generation and the buffer may be selected depending on the pKa of the dye being incorporated. The various embodiments may provide dye-doped polystyrene microspheres, such as KR620-doped polystyrene microspheres that are non-toxic and non-carcinogenic.

  • Patent number: 10669367
    Abstract: An embodiment relates to a polythiol composition for a plastic lens. The polythiol composition for a plastic lens according to the embodiment can produce a clear and transparent plastic lens by way of polymerizing such raw materials as a polythiol compound, an isocyanate, a photoactive color correcting agent, and the like, followed by a simple post-process such as irradiation of ultraviolet rays. In addition, since the process for preparing the lens is simple and economical, the lens is advantageously used for manufacturing various plastic lenses such as eyeglass lenses and camera lenses.

  • Patent number: 10669368
    Abstract: This invention relates to a semi-batch process for the production of polyoxyalkylene polyether polyols. These polyoxyalkylene polyether polyols have hydroxyl (OH) numbers of from 112 to 400. This process comprises establishing oxyalkylation condition in a reactor in the presence of a DMC catalyst, continuously introducing alkylene oxide and a suitable starter into the reactor, and recovering an oxyalkyated polyether polyol. The oxyalkylation initially occurs at a temperature that is sufficiently high enough to avoid or prevent deactivation of the DMC catalyst, or for from 2% to 50% of the total oxide feed amount, and the oxyalkylation is then continued at a lower temperature.
