Summary: Copolymerization of propylene and 1,4‐divinylbenzene was successfully performed by a MgCl 2 ‐supported TiCl 4 catalyst, yielding isotactic poly(propylene) ( i ‐PP) polymers containing a few pendant styrene groups. With a metalation reaction with butyllithium and a hydrochlorination reaction with dry hydrogen chloride, the pendant styrene groups were quantitatively transformed into benzyllithium and 1‐chloroethylbenzene groups, respectively, which allowed the synthesis of i ‐PP‐based graft copolymers by living anionic and atom transfer radical (ATRP) polymerization mechanisms.The incorporation of styrene pendant groups into isotactic poly(propylene) using a Zeigler–Natta catalyst gave functionalized polymers able to undergo living anionic and atom transfer radical (ATRP) polymerizations.
