| Outline of Final Research Achievements |
We developed an effective strategy to control particle size and surface structure for surface-functional polymer particles prepared from various monomers. Novel macromonomers composed of poly(L-glutamic acid) or poly(L-lysine) were successfully synthesized. They were used as a functional stabilizers for the dispersion polymerization of styrene to give narrowly-distributed polystyrene particles on which the polypeptide chains were grafted. It was found that the particle size and the surface density of the resultant particles could be varied by tuning the concentrations of the macromonomer, styrene, and initiator used in the initial solution of the dispersion polymerization. The polypeptide macromonomers were also found to be effective for the dispersion polymerization of various monomers to give high functional and high performance particle cores.
