ABSTRACT Gaining polymer with narrow molecular weight distribution ( Đ ) by efficient living polymerization methods is fundamental and essential in science. Grignard reagent mediated anionic capable of low , however, not suitable for the nonpolar monomers like styrene (St). Here, several kinds additives lithium chloride (LiCl) N,N,N′,N′′,N′′ ‐Pentamethyldiethylenetriamine (PMDETA) are demonstrated as that can promote St. Through LiCl‐promoted polymerization, polystyrene (PS) manipulated successfully achieved under mild conditions full monomer conversion, using a series reagents (RMgX) presence LiCl. In comparison, no PS be prepared absence additive. Electron paramagnetic resonance reveals radical characteristic increased additive, which eventually enables successful St conversion. This work therefore opens simple additive strategy to current method expands library might cause inspirations chemistry.
