Abstract
La présente invention a pour objet un procédé pour la préparation de compositions homogènes sous forme de particules destinées notamment à la confection d'adhésifs fusibles à chaud. Ce procédé est caractérisé en ce qu'on prépare un mélange renfermant de l'eau, les polymères de base entrant dans la composition, l'agent collant, et au moins un agent de suspension, on amène la température de ce mélange aqueux sans agitation jusqu'à une température comprise entre 80 et 250 degrés C, et telle que le ou lesdits polymères thermoplastiques soient sous la forme d'une masse fondue ayant une viscosité assez basse pour se diviser sous l'effet d'une agitation, on soumet alors ledit mélange, en maintenant la temperature sensiblement constante, à une agitation telle que la masse fondue se divise en particules de taille comprise entre 0,005 et 5 mm, puis on refroidit la suspension sous une agitation réduite, et on sépare enfin lesdites particules de la phase aqueuse. Elle concerne la préparation de compositions homogènes sous forme de particules, à base de polymères thermoplastiques, destinées à la confection d'adhésifs fusibles à chaud, du genre désigné généralement sous la dénomination << hot-melt >>.
