Outline of Final Research Achievements

We herein report a new strategy to prepare well-defined graft polymers into solid state plastic films by radiation-induced and atom transfer radical polymerizations (ATRP). To prepare the films with the macro-initiator, 4-chloromethylstyrene was introduced into poly(ether ether ketone) films by radiation-induced polymerization. Then, ATRP of styrene was conducted in acetonitrile using Cu-based catalyst. By adjusting catalyst concentration, grafting degrees of polystyrene linearly increased even at 50 C and reached to 112%. Furthermore, we confirmed the living nature of the propagating graft-polymers in the successive ATRP in solid polymer films.
