A process for the preparation of monodisperse polymer particles which are formed by contacting monomers with aqueous dispersions comprising monodisperse swellable seed polymers/oligomers, and initiating polymerisation in the presence of a steric stabiliser. The resulting swollen seed particles are characterised by the particle mode diameter.
La présente invention concerne un procédé pour préparer des particules polymères monodispersées. Ces particules sont formées par mise en contact de monomères avec des dispersions aqueuses comprenant des polymères/oligomères germes monodispersés qui peuvent gonfler, puis par amorce de la polymérisation en présence d'un stabilisateur stérique. Les particules germes gonflées résultantes sont caractérisées par leur diamètre de mode.
