    Polydispersité de la cellulose de la pâte de bois (1949)
    Hoboken, NJ : Wiley-Blackwell
    Journal of Polymer Science 4 (1949), S. 289-307 
    Details
    ISSN: 0022-3832
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Physics
    Description / Table of Contents: A practical and simple method, with perfectly reproducible results, has been studied for the determination of chain-length repartition of cellulose samples from different wood pulps. By this method, it shall be possible to understand the influence of different factors governing the manufacture and the mechanical properties of our end products.
    Notes: Nous avons étudié une méthode pratique et simple, dont les résultats soient parfaitement reproductibles, de détermination de la répartition des longueurs de chaînes de la cellulose provenant de pâtes de bois différentes. Cette méthode nous permettra de mieux comprendre l'influence des différents facteurs de fabrication sur les qualités mécaniques de nos produits finis.

    Titration potentiometrique de la viscose. II (1948)
    Hoboken, NJ : Wiley-Blackwell
    Journal of Polymer Science 3 (1948), S. 834-849

    Topics: Chemistry and Pharmacology , Physics
    Description / Table of Contents: It has been found, by interpretation of the curve for the potentiometric titration of viscose with 0.1 N AgNO3, that the sulfur compounds of the viscose exist in the “ortho” form. This leads to a new theory for the ripening of viscose.
    Notes: En cherchant à interpréter la courbe expérimentale de la titration potentiométrique de la viscose par l'AgNO3, 0.1 N, on a découvert que les composés sulfurés de la viscose devaient se trouver sous la forme “ortho.” Ceci a permis de proposer une nouvelle théorie du mürissement de la viscose.

    Potentiometric titration of viscoseTranslated from the original French. Part II of this paper will appear in THIS JOURNAL under the title of “La Conductivité Électrique de la Viscose.” (1948)
    Hoboken, NJ : Wiley-Blackwell
    Journal of Polymer Science 3 (1948), S. 487-499

    Notes: A new method is investigated to determine by means of potentiometric titration the degree of ripening of viscose. It is found that when the e.m.f. of a characteristic inflection in the potentiometric titration curve is plotted against a measure of the degree of viscose ripening a sharp minimum occurs at a point corresponding to the optimal degree of ripening. Moreover, evidence is offered to indicate the formation of sodium dithiocarbonate in viscose during ripening. This last fact leads to a reasonable postulation of the complete scheme of reactions taking place in a ripening viscose.
