Title (EN) POLYMER COMPOSITIONS HAVING IMPROVED PROCESSABILITY AND METHODS OF MAKING AND USING SAME
(FR) COMPOSITIONS DE POLYMÈRE PRÉSENTANT UNE APTITUDE AU TRAITEMENT AMÉLIORÉE ET LEURS PROCÉDÉS DE FABRICATION ET D'UTILISATION
Abstract:
(EN) A method of preparing a polymer article comprising determining a zero-shear viscosity for a polymer sample; sieving the polymer sample to produce a plurality of sieved polymer samples; determining a molecular weight distribution for each of the plurality of sieved polymer samples; determining a zero-shear viscosity for each of the plurality of sieved polymer samples; determining a compositional diversity of each of the plurality of sieved polymer samples based on a ratio of the zero shear viscosity for each of the plurality of sieved polymer samples to the zero shear viscosity for the polymer sample; identifying a polymer sample having a ratio of the zero shear viscosity to zero shear viscosity for the polymer sample of from about 0.5 to equal to or greater than about 3; and preparing a polymer article from the identified polymer sample.
(FR) L'invention concerne un procédé de préparation d'un article polymère, qui consiste: à déterminer une viscosité à cisaillement nul pour un échantillon de polymère, à cribler l'échantillon de polymère afin de produire une pluralité d'échantillons de polymère criblés; à déterminer une distribution de poids moléculaire pour chaque échantillon de la pluralité d'échantillons de polymère criblés; à déterminer une viscosité à cisaillement nul pour chaque échantillon de la pluralité d'échantillons de polymère criblés; à déterminer une diversité compositionnelle de chaque échantillon de la pluralité d'échantillons de polymère criblés, sur la base d'un rapport de la viscosité à cisaillement nul pour chaque échantillon de la pluralité d'échantillons de polymère criblés à la viscosité à cisaillement nul pour l'échantillon de polymère; à identifier un échantillon de polymère dont le rapport de la viscosité à cisaillement nul à la viscosité à cisaillement nul pour l'échantillon de polymère est d'environ 0,5 à égale ou supérieure à environ 3; et à préparer un article polymère à partir de l'échantillon de polymère identifié.
