Abstract
AbstractPreviously, we have reported a one‐pot approach to generate star‐shaped polymers by copolymerization of a maleimide inimer or bismaleimide hexane (BMIH) and a large excess of styrene (St) via atom transfer radical polymerization. Herein, we extended this approach towards the synthesis of star polystyrene through reversible addition fragmentation chain‐transfer (RAFT)‐mediated radical copolymerization of BMIH and an excess of St with cumyl dithiobenzoate (CDB) as a chain‐transfer agent (CTA). It was illustrated that the PS arms were grafted from the preformed core, which was formed in situ during the copolymerization of BMIH and St. Therefore, this facile one‐pot approach can be performed by applying different type of controlled radical polymerization. However, linear PS still was generated as a byproduct which had been observed previously.magnified image
