Title (EN) METHOD FOR FORMING SURFACE DECORATED PARTICLES
(FR) PROCÉDÉ DE FORMATION DE PARTICULES DÉCORÉES EN SURFACE
Abstract:
(EN) A method for forming surface decorated particles including stabilizing dispersed hydrophobic phase particles in an aqueous phase with fine inorganic particles having a relatively hydrophilic surface; and treating the stabilized dispersed hydrophobic phase particles with a hydrophobic group containing reactant to form hydrophobic groups covalently bonded to surfaces of the fine inorganic particles. In a particular embodiment, the invention provides a limited coalescence process for preparing binder polymer particles using inorganic stabilizer particles that provide a plurality of surface bonding sites and reacting such sites with a plurality of alkoxy silane moieties that contains pendant hydrophobic groups.
(FR) L'invention concerne un procédé servant à former des particules décorées en surface consistant à stabiliser des particule en phase hydrophobe dispersées dans une phase aqueux avec des particules inorganiques fines dont la surface est relativement hydrophile ; et à traiter les particules en phase hydrophobe dispersées avec un groupe hydrophobe contenant un réactif pour former des groupes hydrophobes en liaison covalente à la surface des particules inorganiques fines. Dans un mode de réalisation particulier, l'invention concerne un processus de coalescence limitée servant à préparer des particules de polymère liantes utilisant les particules inorganiques stabilisantes qui produisent une pluralité de sites de liaison en surface et en faisant réagir de tels sites avec une pluralité de groupes caractéristiques alkoxy silane qui contiennent des groupes hydrophobes pendants.
