CA 2565922

This invention discloses a process and a necessary article to simultaneously thermally treat at least two thermoplastics. The process utilizes the necessary compartmentalized or zoned pellet construction wherein the major amount of each thermoplastic component is located within individual compartments or zones of the pellet such that the components of the reaction during thermal processing and/or reactions with compounds in the atmosphere such as oxygen are less than the reaction if the thermoplastics were homogeneously dispersed in the pellet. This invention allows the components of the multi-component pellets to be thermally treated together without significant degradation and/or stored in air or in the presence of oxygen without significant degradation.

La présente invention concerne un procédé et un article indispensable pour traiter simultanément au moins deux thermoplastiques. Le procédé met en oeuvre la construction indispensable de granulé compartimentée ou zonée dans laquelle la majeure partie de chaque composant thermoplastique se trouve à l'intérieur de compartiments ou de zones individuels du granulé, de manière que les composants de la réaction lors du traitement thermique et/ou des réactions avec des composés dans l'atmosphère, tel que de l'oxygène, sont moins nombreux que si les thermoplastiques de la réaction avaient été dispersés de manière homogène dans le granulé. Cette invention permet de pouvoir soumettre conjointement à un traitement thermique des granulés à plusieurs composants sans induire de dégradation importante et/ou de pouvoir les stocker à l'air ou en présence d'oxygène sans induire de dégradation importante.
