    Description / Table of Contents: Zusammenfassung Verfasser versuchte die Kontraktionsspannung in eine Formel zu bringen unter der Bedingung, daß der Elastizitätsmodul, der Kontraktionskoeffizient und die Relaxationszeit Funktionen der Zeit sind. Aus der Formel ließ sich folgern, daß die Härtungsgeschwindigkeit auf die Kontraktionsspannung Einfluß hat. Zugleich wurde ein auf einer Methode vonInoue-Kobatake beruhendes Experiment angestellt und ergab das gleiche Resultat.
    Notes: Summary The author intended to compose the expression about contractive stress with the condition that the modulus of elasticity, volume contraction and relaxation time are functions of time, then deduced from the expression that the rate of curing has an effect on the contractive stress. In addition the experiment byInoue-Kobatake's method was made.

    Notes: Copolyamide-esters (CPAEs) were synthesized by the amide-ester interchange reaction. The change of intrinsic viscosity during CPAE synthesis was negligible. Polyamide blocks were shortened with increasing reaction time and polyester content. The polymerization degree of nylon 12 blocks on CPAE was smaller than that of nylon 6 blocks. CPAEs were hydrolyzed by Rhizopus delemar lipase. The biodegradability decreased with the shortening of the polyamide blocks and with increasing polyamide content. It was concluded that the amount and distribution of the hydrogen bonds, based on the amide group, in the CPAE chains strongly influenced their biodegradation by this lipase.
