    Description / Table of Contents: Unperturbed dimensions of poly(tetramethylene adipate). poly(octamethylene sebacate) und poly(ε-caprolactone) have been determined by 5 different methods in the temperature range between 18 and 35°C. The unperturbed dimensions were independent of the method applied. The characteristic constant C∞ increases with increasing content of methylene groups. The flexibility of the polyesters thus decreases with decreasing content of ester groups.
    Notes: Die ungestörten Dimensionen von Polytetramethylenadipat, Polyoctamethylensebacat und Poly-ε-caprolacton wurden nach fünf verschiedenen Methoden im Temperaturbereich zwischen 18 und 35°C ermittelt. Sie erwiesen sich für jede Probe als unabhängig von der verwendeten Methode. Mit steigendem Gehalt der Polyester an Methylengruppen nimmt die charakteristische Konstante C∞ zu und daher die Flexibilität der Polyester ab.
