Two is better than one : Repetitive ABA sequences in copolymers were obtained by a palladium‐templated monomer. Crucial in the polymerization were π–π‐stacking interactions between aromatic side groups to array three vinyl groups (see picture). Because of the interactions double cyclopolymerization at the palladium‐templated monomer was possible. Removal of the template led to sequence‐regulated copolymers.
