Title
(EN) COATED GRANULES PRODUCED BY IN-SITU CROSSLINKING PROCESS
(FR) GRANULÉS ENROBÉS PRODUITS PAR UN PROCÉDÉ DE RÉTICULATION IN SITU
Abstract
(EN) Described are compositions and methods relating to a coated granule comprising a core coated with cross-linkable polymer, where the cross-linkable polymer is applied using a feed suspension that includes an acid-neutralized volatile base and a calcium salt insoluble at the pH of the neutralized feed suspension. Volatilization of the base decreases the pH of the feed suspension, thereby solubilizing the calcium salt, and inducing in situ ion-mediated cross-linking of the cross-linkable polymer.
(FR) L'invention concerne des compositions et des procédés se rapportant à un granulé enrobé comprenant un noyau revêtu d'un polymère réticulable, le polymère réticulable étant appliqué à l'aide d'une suspension de charge qui comprend une base volatile neutralisée par un acide et un sel de calcium insoluble au pH de la suspension de charge neutralisée. La volatilisation de la base diminue le pH de la suspension de charge, ce qui permet de solubiliser le sel de calcium, et d'induire une réticulation médiée par des ions in situ du polymère réticulable.
