Title
(EN) REACTIVE PURGE COMPOUND FOR POLYMER PURGING
(FR) COMPOSÉ DE PURGE RÉACTIVE POUR PURGE DE POLYMÈRE
Abstract
(EN)
The present invention relates to reactive purge compound for cleaning polymer processing equipment wherein the reactive purge compound that includes at least about 50 wt.% of a polymeric carrier component based on the total weight of the reactive purge compound, wherein the polymeric carrier component includes one or more polymers; a chain scission catalyst component dispersed in the polymeric carrier component; and iii) a water generating component; wherein the reactive purge compound is a feedstock material in the form of a plurality of pellets, granules, rods, powder or other particles.
(FR)
La présente invention porte sur un composé de purge réactive pour nettoyer un équipement de traitement de polymère, le composé de purge réactive comprenant au moins environ 50 % en poids d'un constituant porteur polymère sur la base du poids total du composé de purge réactive, le constituant porteur polymère comprenant un ou plusieurs polymères; un constituant catalyseur de scission de chaîne dispersé dans le constituant porteur polymère; et iii) un constituant générant de l'eau; le composé de purge réactive étant un matériau de charge se présentant sous la forme d'une pluralité de pastilles, granulés, bâtonnets, poudre ou autres particules.
