Firstly, a commercial flow reactor was used to synthesize poly(PEGMEMA) via RAFT polymerization. The tunable pressure makes it possible to conduct polymerization at high temperature in aqueous solution. Compared with the same reaction in conventional batch reactor, this flow system can lead to higher polymerization efficiency. The flow rate and initiator concentration were also well studied to tune the monomer conversion and the molar mass dispersity (Ð) of the obtained polymers. Poly(PEGMEMA) and poly(PEGMEMA)-b-PNIPAM brushes were also grafted from the silica microparticles by such continuous system at high temperature with increased pressure. The flowing nature makes it possible to conduct multi-step reactions with simple purification process which saves time and cost. TGA, FT-IR, SEM were utilized to characterize the polymer modified microparticles. GPC and NMR were also used to measure the brushes cleaved from particles.
