    Description / Table of Contents: Die Löslichkeitsparameter von Polyacrylsäuremethyl-, -äthyl-, -propyl- und -butylester wurden mittels Messungen ihrer Lösungsviskositäten in einer Reihe von Alkylestern als Lösungsmittel bestimmt. Die Ergebnisse stimmen gut mit jenen überein, die man über Quellungsmessungen erhielt. Es wurde beobachtet, daß in einer homologen Reihe die Kohäsionsenergiedichten mit zunehmender Kettenlänge des Alkohols abnehmen.
    Notes: The solubility parameters of polymethyl, -ethyl, -propyl, and -butyl acrylates were estimated by measuring their solution viscosities in a series of alkyl ester solvents. The results agreed well with those obtained by swelling measurements and it was observed that in the homologous series, c.e.d.8 decreases with increase in the alcoholic chain length.

    Description / Table of Contents: Die Kohäsionsenergiedichten (c.e.d.) mehrerer Polyacrylate und Polymethacrylate wurden durch Quellungsmessungen in einer Reihe von Alkylestern bestimmt. Die Werte für die Kohäsionsenergiedichten sind für die Polyacrylate höher als für die Polymethacrylate. In einer Art homologer Reihe nehmen die c.e.d.-Werte ab mit zunehmender Länge der alkoholischen Kette.
    Notes: The cohesive energy densities (c.e.d.) of a number of polyacrylates and polymethacrylates have been estimated by swelling measurements in a series of alkyl esters. It is seen that the magnitudes of c.e.d. for polyacrylates are higher than those for polymethacrylates and in a homologous series, c.e.d. decreases with increase in the length of the alcoholic chain.
