摘要: The solid state polymerization of bis(p-toluene sulphonate)diacetylene proceeds via a single-phase solution. optical constants the pleochroic partially polymerized crystals are determined. Spurious “absorption lines”, due to an intense Brewster's brush, observed, especially when increasing polymer content leads pronounced dispersion optic axes. fully for light polarized parallel conjugated chains calculated from reflection spectra. These data enables principal values absorption ellipsoid be determined and compared with theoretical predictions. Die Festkorperpolymerisation von bis(p-Toluol-Sulfonsaureester)-Diacetylen erfolgt uber eine einphasige feste Losung. Die optischen Konstanten der pleochromen, teilweise polymerisierten Kristalle werden bestimmt. Vorgetauschte “Absorptionen” durch ein intensives “Brewster-Buschel” besonders dann beobachtet, wenn zunehmende Polymergehalt zu ausgepragter Dispersion Achsen fuhrt. vollstandig Kristallen fur den konjugierten Polymerketten polarisiertes Licht aus Reflexionsspektren berechnet. Anhand dieser Daten ist es moglich, die Hauptwerte des Absorptionsellipsoids Ketten bestimmen und mit theoretischen Vorhersagen vergleichen.
