Method of polymerising a monomer at the surface of a particulate material, method of preparing paint and a paint

摘要

Polymer encapsulated particulate material that is 100 microns or less in size, wherein:
(a) said particulate material is encapsulated in a substantially uniform and continuous coating of a polymer which has at least in part been formed under the control of a RAFT agent; or
(b) the polymer which encapsulates the particulate material has at least in part been formed under the control of a RAFT agent, and wherein the particulate material is substantially uniformly dispersed throughout the polymer.
