What is Alternating Copolymerization of Styrene and Methyl α-Chloroacrylate with Diethylaluminum Chloride about?
## Abstract The alternating copolymerization of styrene and methyl α‐chloroacrylate (MCA) with diethylaluminum chloride (Et~2~AlCl) in benzene at 0°C has been investigated. The copolymer has an equimolar composition irrespective of the feed monomer composition, the copolymer yield and the amount of Et~2~AlCl used. The copolymerization proceeds first very rapidly and then rather slowly after attaining a certain yield which varies proportionally to the amount of Et~2~AlCl used. A maximum copolymer yield is observed at about 60% MCA feed composition. The ^1^H‐NMR analyses of dyad, triad, and pentad of the alternating deuterated α‐__d__‐St‐MCA copolymer indicate that the configuration of this copolymer can be explained by a single parameter, coisotacticity σ(σ = 0.69). A favorable mechanism of the alternating propagation as well as of the stereoregularity control is discussed.
