Encapsulated polymer particles |
| abstract |
The present invention relates to a method of preparing an aqueous dispersion of polymer encapsulated particulate material, the method comprising: providing a dispersion of the particulate material in a continuous aqueous phase, the dispersion comprising ethylenically unsaturated monomer and a stabiliser for the particulate material; and polymerising the ethylenically unsaturated monomer by non-living free radical polymerisation to form polymer that encapsulates the particulate material, thereby providing the aqueous dispersion of polymer encapsulated particulate material; wherein polymerisation of the ethylenically unsaturated monomer comprises: (a) polymerising a monomer composition that includes ionisable ethylenically unsaturated monomer so as to form a base responsive water swellable non-living polymer layer that encapsulates the particulate material; and (b) polymerising a monomer composition that includes non-ionisable ethylenically unsaturated monomer so as to form an extensible, water and base permeable non-living polymer layer that encapsulates the base responsive water swellable polymer layer. |
