Polymer particles |
| abstract |
The present invention relates to a method of forming polymer on the surface of polymer particles, the method comprising:n (i) providing a dispersion comprising a continuous aqueous phase, a dispersed organic phase comprising one or more ethylenically unsaturated monomers, and a RAFT agent as a stabiliser for said organic phase; (ii) polymerising the one or more ethylenically unsaturated monomers under the control of the RAFT agent to form an aqueous dispersion of seed polymer particles; (iii) crosslinking the seed polymer particles; (iv) swelling the crosslinked seed particles with one or more ethylenically unsaturated monomers to form an aqueous dispersion of monomer swollen crosslinked seed polymer particles; (v) increasing the temperature of the monomer swollen crosslinked seed polymer particles to expel at least some of the monomer therein onto the surface of the particles; andn npolymerising at least the expelled monomer to form polymer on the surface of the particles. |
