Combining RAFT Dispersion Polymerization and Surface-Initiated ATRP for Surface Engineering of Polymeric Microspheres

-dimethylacrylamide) (PDMA), and poly(poly(ethylene glycol) methyl ether methacrylate) (PPEGMA), without loss of particle uniformity. Incorporation of trithiocarbonate-containing comonomers via surface-initiated ATRP further allowed orthogonal surface-initiated RAFT polymerizations to generate graft copolymer architectures. This modular ATRP-RAFT approach affords precise control over the microsphere morphology and surface chemistry, providing a versatile platform for constructing functional polymeric microspheres for various applications.
