| Research Abstract |
We succeeded in preparing various non-spherical polymer particles by emulsion and seeded polymerization. Among these particles, “mushroom”-like polymer particles were prepared by seeded Atom Transfer Radical Polymerizaion（ATRP）of 2-(dimethylamino)ethyl methacrylate (DM) in the presence of hemispherical (“Janus”) poly(methyl methacrylate) (PMMA)/poly[styrene-2-(2-bromoisobutyryloxy)ethyl methacrylate] [P(S-BIEM)] composite particles in an aqueous dispersed system. The obtained composite particles had a Janus morphology: PDM layer only on the surface of P(S-BIEM) phase. We also demonstrated that PMMA/P(S-BIEM)-g-PDM Janus particles exhibit dual responsiveness to pH and temperature.
