标题 :Process for the production of graft polymers
发明人：WENZ ECKHARD; BUCHHOLZ VERA; EICHENAUER HERBERT; WOLF UDO; BORN RALF-JURGEN; JANSEN ULRICH; DIETZ WOLFGANG
摘要:A process of preparing a graft polymer (e.g., an ABS graft copolymer), which involves determining the concentration of at least one reaction component during the course of the reaction by means of Raman spectroscopy, is disclosed. The process, more particularly, comprises: (a) synthesizing the graft polymer from a reaction mixture comprising reactive components (e.g., monomers such as styrene and acrylonitrile, and a graft base); (b) analyzing the reaction mixture, at intervals, during the synthesis of the graft polymer, by means of Raman spectra; (c) recording the results of the Raman spectra analysis; (d) determining the concentration of at least one of said reactive components (e.g., styrene) by means of spectral evaluation of the recorded Raman spectra; and (e) terminating the synthesis reaction of the graft polymer when the concentration of at least one of the reactive components has reached a predetermined concentration value.

摘要:Various embodiments provide epoxy modified fluorinated urethane compositions that may provide desirable bulk mechanical properties of conventional coatings, adhesives, or structural matrix resins, while simultaneously exhibiting surface properties that may reduce surface contamination. Various embodiments provide formulations comprising epoxy modified fluorinated alkyl ether including urethane oligomer or polymer resins that may possess the requisite thermal, mechanical, chemical, and optical properties while achieving a low surface energy. In various embodiments, such resins may be prepared from random urethane oligomer compositions including fluorinated alkyl ether segments, in which the oligomers may be terminated with amino groups and subsequently reacted with epoxy including monomers or oligomers.

摘要:A method for managing skin tone comprising reducing the synthesis of melanin by applying a skin treatment composition to skin. The skin treatment composition may include about 0.1 to about 25 wt. % of acetyl trifluoromethylphenyl valylglycine; about 0.5 to about 30 wt. % of a polyol; about 0.1 to about 30 wt. % of a silicone, fatty compound, or a mixtures thereof, wherein the skin treatment composition is an emulsion, and all weight percentages are based on the total weight of the skin treatment composition.
