Band substances : The polymerization of C 3 O 2 (see picture left, at −10 °C) into a red‐brown, solid polymer (right) having identical composition has been known for almost 100 years. However, the constitution of the polymer remained unknown. Small‐angle X‐ray scattering studies of the dissolved polymer show that it forms a stiff bandlike molecule with approximately 40 monomeric units, thus confirming the predicted bandlike structure with condensed α‐pyrone rings.
