发明人：ZHU NING; STAMMER ACHIM; CLAUSS JOACHIM; KORY GAD
权利人:BASF SE
摘要:An apparatus for synthesis of a polymer with separation of a gaseous substance comprises a reaction space having an essentially circular cylindrical upper section which is bounded by two circular faces and one shell face and has a longitudinal cylinder axis, and a lower section, an inlet orifice disposed in a circular face or the shell face of the upper section, a first outlet orifice disposed in a wall of the lower section, a second outlet orifice disposed in the shell face of the upper section opposite the first outlet orifice, and a removal device which is disposed so as to be rotatable about the longitudinal cylinder axis and is in contact with both circular faces and the shell face. This apparatus can especially be used for performance of a process including the feeding of an oligomer melt into a reaction space through an inlet orifice, the polymerization of the oligomer melt to give a polymer melt, the removal of the polymer melt from the reaction space through a first outlet orifice of the reaction space, and the removal of a gaseous substance from the reaction space through a second outlet orifice of the reaction space, wherein deposits on at least one inner wall of the reaction space are removed by a removal device and transported into the oligomer melt.

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:Provided are a preparation method of an epoxy compound having an alkoxysilyl group in which an increase in the epoxy equivalent weight (EEW) of the epoxy compound is minimized because alkoxysilylation occurs through a simple one-step reaction using a hydroxyl group formed during the synthesis of the epoxy compound, an epoxy compound having an alkoxysilyl group prepared by the method, a composition comprising the same, and a use thereof. The method includes the reaction of an epoxy compound having a hydroxyl group with an isocyanate alkoxysilane in the presence of amine-based base catalyst, wherein the epoxy compound having an alkoxysilyl group has a mole ratio of [epoxide group]:[alkoxysilyl group] of n:1 ranging from 2:1 to 10:1, and an EEW increase of the epoxy compound having an alkoxysilyl group is less than 260/n. The epoxy compound has good physical properties when being cured.
