    Notes: The formation of certain low molecular weight by-products during the esterification reaction between ethylene glycol and dimethyl terephthalate was investigated. The result obtained showed that the presence of incorporated diethylene glycol within the polymer led to the formation of low molecular weight side products. An alcoholysis reaction involving the ethylene glycol and the ester was found to show a mechanism that is analogous to that of an ester interchange resulting in the production of the acid and the diethylene glycol precursor of the dioxane by-product.

    Notes: Changes brought about in the crystal morphology of drawn (oriented) PET fibers following both heat and liquid treatments were studied using wide angle X-rays and critical dissolution time techniques. The results obtained showed that the two techniques were sensitive to different but closely related morphological properties of the polymer, the former being sensitive to the apparent degree of the crystalline content, and the latter, a measure of the size of such crystallites that were produced.

    Description / Table of Contents: Poly(ethylenterephthalat)-Fasern wurden isotherm mit Dimethylformamid bei 80°C und 120°C behandelt. Die Behandlung bewirkte einen beträchtlichen Längsschrumpf und Änderungen der mechanischen Eigenschaften der Fasern. Die Aufnahme eines Dispersionsfarbstoffs wurde durch die Vorbehandlung mit Dimethylformamid verstärkt. Die mit Lösungsmittel behandelten und gefärbten Fasern zeigten eine verbesserte elastische Erholung.
    Notes: Poly(ethylene terephthalate) fibres were isothermally treated with dimethyl formamide at 80°C and 120°C. The treatment resulted in considerable shrinkage of the length and in modifications of the mechanical properties of the filaments. The uptake of a disperse dyestuff was enhanced by the pretreatment with dimethyl formamide. The solvent treated and dyed fibres showed improved elastic recovery.
