Main‐chain ionic polymers incorporating chiral imidazolidinone moieties in the polymermainchain were successfully synthesized by the polyaddition reaction of a chiral imidazolidinone dimer with a disulfonic acid. The organocatalytic activities of these polymers were investigated in the asymmetric Diels–Alder reaction between trans‐cinnamaldehyde and 1,3‐cyclopentadiene. The catalytic performance
