The size of both the cation and the anion of added NR 4 X influences the rate of living polymerization of acrylates and methacrylates with alkylaluminum compounds. This controlled reaction, which occurs near to room temperature, provides unimodal polymers with narrow molecular‐weight distributions. The complex shown to the right is suggested as a possible active species. R=Me, Et, n Bu; R′=Me, Et; X=Cl, Br, I.
