Title: POLYMER BEADS AND APPLICATION THEREOF
Abstract:
The present invention relates to a process for producing polymer beads having a porous polymeric matrix in which is distributed solid particulate material; the process comprising: (i) providing a dispersion having a dispersed phase and a continuous phase, the dispersed phase comprising: (a) polymerisable monomer composition, (b) solid particulate material, (c) non-polymeric porogen; and (d) no polymeric porogen; wherein the polymerisable monomer composition comprises; (e) at least one mono-ethylenically unsaturated monomer, and (f) at least one crosslinking monomer having at least two ethylenically unsaturated groups that are separated by at least 4 consecutive acyclic atoms; and (ii) polymerising the polymerisable monomer composition in the presence of the non- polymeric porogen and solid particulate material to form the porous polymeric matrix of the beads.
