| Abstract: | Two poly(4‐methylstyrene) (P4MS)‐block‐polystyrene (PS)‐block‐P4MS triblock copolymers were prepared by successive anionic addition of styrene and 4‐methylstyrene monomers as the core backbone ( CB ) for the architecture of block‐graft polymers. Both terminal 4‐methylstyrene blocks of CB were metalated with a sec‐butyllithium (sec‐BuLi)/tetramethylethylenediamine (TMEDA) complex in cyclohexane. The first‐generation block‐graft polymer ( 1BG ) was prepared by anionic polymerization of α‐methylstyrene by the lithiated CB in tetrahydrofuran (THF) at –78°C and subsequently the terminal graft ends were capped with a small amount of 4‐methylstyrene. The characterization of those block‐graft polymers was carried out in detail. |
