The present invention relates to a process for producing polymer beads incorporating solid particles and to the novel polymer beads per se. The invention provides a process for producing polymer beads incorporating solid particulate material, which process comprises producing a dispersion having a dispersed phase including one or more monomers also including solid particulate material and causing said one or more monomers to undergo a polymerisation reaction to form said polymer beads, wherein said dispersion further includes a solid phase dispersing agent for dispersing solid particles of material in the dispersed phase and wherein said solid phase dispersing agent reacts with at least one monomer to thereby become chemically incorporated in said polymer. The polymer beads comprise a polymer matrix having solid particulate material dispersed substantially uniformly therein and wherein the polymer matrix incorporates a solid phase dispersing agent chemically reacted into the polymeric matrix.
L'invention concerne un procédé, qui permet de produire des perles polymères renfermant des particules solides, et ces perles polymères qui sont nouvelles. Ce procédé consiste à produire une dispersion comprenant une phase dispersée qui contient un ou plusieurs monomères et un matériau à particules solides, puis à faire subir à ce ou ces monomères une réaction de polymèrisation destinée à former ces perles polymères. Cette dispersion contient aussi un dispersant en phase solide qui disperse les particules solides du matériau dans la phase dispersée. Ce dispersant réagit avec un monomère au moins pour s'incorporer chimiquement dans le polymère. Les perles polymères comportent une matrice polymère, où le matériau à particules solides est dispersé de façon virtuellement uniforme, matrice qui contient le dispersant en phase solide ayant subi une réaction chimique.
