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. Citing Literature Volume21, Issue10June 2000Pages 660-664 RelatedInformation
