Title (EN) POLYMER COMPOSITIONS HAVING IMPROVED PROCESSABILITY AND METHODS OF MAKING AND USING SAME
(FR) COMPOSITIONS POLYMÈRES PRÉSENTANT UNE APTITUDE AU TRAITEMENT AMÉLIORÉE ET LEURS PROCÉDÉS DE FABRICATION ET D'UTILISATION
Abstract:
(EN) A method of preparing a polymer article comprising preparing a plurality of polymer samples having a lower molecular weight (LMW) component and a higher molecular weight (HMW) component; sieving each of the plurality polymer samples to produce a corresponding plurality of sieved polymer samples; determining a heterogeneity value for each of the plurality of polymer samples; identifying at least one polymer sample from the plurality of polymer samples having a predicted gel count of less than 100 gels/ft2 wherein the predicted gel count is a function of the heterogeneity value; and fabricating a film from the identified polymer sample having a predicted gel count of less than about 100 gels/ft2.
(FR) L'invention concerne un procédé de préparation d'un article polymère comprenant la préparation d'une pluralité d'échantillons polymères présentant un constituant de faible poids moléculaire (LMW) et un constituant de poids moléculaire élevé (HMW); le tamisage de chaque échantillon polymère de la pluralité d'échantillons polymères de manière à produire une pluralité correspondante d'échantillons polymères tamisée; l'estimation d'une valeur d'hétérogénéité pour chaque échantillon polymère de la pluralité d'échantillons polymères; l'identification d'au moins un échantillon polymère provenant de la pluralité d'échantillons polymères doté d'une teneur en gel prédite inférieure à 100 gel/pied2, la teneur en gel prédite dépend de la valeur d'hétérogénéité; et la fabrication d'un film à partir de l'échantillon polymère identifié présentant une teneur en gel prédite inférieure à environ 100 gel/pied2.
