    Description / Table of Contents: Um den Permeationsmechanismus von Flüssigkeit durch Polypeptidmembranen zu erhellen, wurde die Permeation von n-Alkoholen durch Poly(γ-alkyl-L-glutamat)-Membranen aus Methyl-, Ethyl- und Benzylglutamaten unter Variation der Betriebstemperatur untersucht. Es wurde gefunden, daß eine signifikante Wechselwirkung zwischen den Estergruppen der Seitenkette von Poly(γ-alkyl-L-glutamat) und dem Alkoholmolekül besteht. Diese Wechselwirkung beeinflußt deutlich die Permeations-geschwindigkeit von Alkoholen und die Trennungseigenschaften von Alkohol-mischungen.
    Notes: To reveal the permeation mechanism of liquids through polypeptide membranes, the permeation of n-alcohols through poly(γ-alkyl L-glutamate) membranes such as the polymers of methyl, ethyl, and benzyl glutamates was investigated by changing the operating temperature. It was found that there was a significant interaction between the ester groups of the side chain of poly(γ-alkyl L-glutamate) and the alcohol molecule. This interaction affected significantly the permeation rates of alcohols and the separation characteristics of alcohol mixtures.
