Title (EN) ADHESIVE COMPOSITIONS
(FR) COMPOSITIONS ADHÉSIVES
Abstract:
(EN) The invention is directed to a method for preparing an adhesive composition, in which an aqueous phase comprising a modified colloidal silica is mixed with an organic phase comprising one or more monomers in the presence of an initiator, wherein conditions are maintained such that polymerisation of the one or more monomers occurs to form an aqueous polymeric dispersion, wherein; (i) the aqueous polymeric dispersion comprises polymer particles with protective colloid on their surface; (ii) the modified colloidal silica comprises colloidal silica particles with at least one surface-bound hydrophilic organosilane moiety and/or comprises colloidal silica particles with at least one additional element on its surface, the element being able formally to adopt a +3 or +4 oxidation state; and (ill) the initiator is at least partially soluble in water. The invention is also directed to an adhesive composition which can be made by the above method, wherein at least a portion of the colloidal silica particles chemically interact with the protective colloid.
(FR) L'invention concerne un procédé de préparation d'une composition adhésive, dans lequel une phase aqueuse comprenant une silice colloïdale modifiée est mélangée à une phase organique comprend un ou plusieurs monomères en présence d'un amorceur, les conditions étant maintenues de façon que la polymérisation du ou des monomères se produise pour former une dispersion polymère aqueuse, procédé dans lequel : (i) la dispersion polymère aqueuse comprend des particules polymères comportant un colloïde protecteur sur leur surface ; (ii) la silice colloïdale modifiée comprend des particules de silice colloïdale comportant au moins un fragment organosilane hydrophile lié en surface et/ou comprend des particules de silice colloïdale comportant au moins un élément additionnel sur leur surface, l'élément étant capable formellement d'adopter un état d'oxydation +3 ou +4 ; et (iii) l'amorceur est au moins partiellement soluble dans l'eau. L'invention concerne également une composition adhésive qui peut être fabriquée par le procédé ci-dessus, au moins une partie des particules de silice colloïdale interagissant chimiquement avec le colloïde protecteur.
