Title (EN) METHOD OF SUSPENSION POLYMERIZATION OF DROPLETS DISTRIBUTED IN AN AQUEOUS MEDIUM
(FR) PROCÉDÉ DE POLYMÉRISATION EN SUSPENSION DE GOUTTELETTES DISTRIBUÉES DANS UN MILIEU AQUEUX
Abstract:
(EN) Provided is a method of suspension polymerization comprising (I) providing a composition comprising droplets distributed in an aqueous medium, wherein the droplets comprise one or more boronic acids, one or more monomers, and one or more initiators, and wherein the aqueous medium comprises polyvinyl alcohol; wherein the one or more boronic acids are present in an amount of 0.002% or more, by weight based on the weight of the droplets, and (II) stressing the composition so that the initiator initiates polymerization of the monomer.
(FR) La présente invention concerne un procédé de polymérisation en suspension comprenant les étapes consistant à : (I) fournir une composition comprenant des gouttelettes distribuées dans un milieu aqueux, les gouttelettes comprenant un ou plusieurs acides boroniques, un ou plusieurs monomères, et un ou plusieurs amorceurs, et le milieu aqueux comprenant de l'alcool polyvinylique ; le ou les acides boroniques étant présents à hauteur de 0,002 % ou plus en poids sur la base du poids des gouttelettes, et (II) solliciter la composition de sorte que l'initiateur déclenche la polymérisation du monomère.
