Title (EN) HOLLOW POLYMER COMPOSITION
(FR) COMPOSITION DE POLYMÈRE CREUX
Abstract:
(EN) Provided is method of making a hollow polymer composition, comprising the steps of (a) providing an aqueous dispersion comprising (i) hollow polymer particles, wherein the hollow polymer particles comprise polymerized units of one or more multivinyl monomer, (ii) water, and (iii) one or more organic alcohol, and (b) removing water from the aqueous dispersion to form a dry composition comprising the hollow polymer particles and the alcohol, wherein either water is absent from the dry composition or else water is present in the dry composition in an amount such that the weight ratio of water to hollow polymer particles is 0.2:1 or less. Also provided are dry compositions that could be made by such a method, and non-aqueous dispersions of such dry compositions.
(FR) L'invention concerne un procédé de fabrication d'une composition de polymère creux, comprenant les étapes de (a) fourniture d'une dispersion aqueuse comprenant (i) des particules polymères creuses, les particules polymères creuses comprenant des motifs polymérisés d'un ou plusieurs monomères polyvinyliques, (ii) de l'eau, et (iii) un ou plusieurs alcools organiques, et (b) élimination de l'eau de la dispersion aqueuse pour former une composition sèche comprenant les particules polymères creuses et l'alcool. L'eau est absente de la composition sèche ou bien l'eau est présente dans la composition sèche dans une quantité telle que le rapport en poids de l'eau aux particules polymères creuses est de 0,2:1 ou moins. L'invention concerne également des compositions sèches qui pourraient être fabriquées par un tel procédé, et des dispersions non aqueuses de ces compositions sèches.
