  • Patent number: 7122379
    Abstract: A method of using Raman Spectra for determining the progress of a graft polymerization reaction is disclosed. The method entails (a) measuring at the beginning of the reaction and at a plurality of time intervals in the course of the reaction, continuously and on-site, the Raman spectrum in the wave number range of 100 to 4000 cm?1 of one or more of the monomers and/or polymers entailed in the reaction and of at least one internal standard and (b) recording the spectra and (c) adding reaction partners necessary to the reaction continuously and/or discontinuously and (d) calculating the change in concentration of the monomers and polymers by comparing the spectra of the monomers or polymers with the internal standard.

  • Publication number: 20050098007
    Abstract: An installation for removing shavings and remainder pieces from desired cut material after cutting by means of a circular saw with a plurality of saw blades. A conveyor belt longitudinally conveys the cut material downstream of the circular saw. One longitudinal edge of the conveyor belt is aligned with the reference line of the far-right engaged or far-left engaged saw blade. A pusher unit with stop, which can be displaced transversely with respect to the longitudinal direction of the conveyor belt, is arranged on the aligned side downstream of the circular saw.

  • Publication number: 20030130433
    Abstract: 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.
