The direct aldol polymerization of acetaldehyde, a new approach for the synthesis of poly(vinyl alcohol)‐ and poly(vinyl alcohol‐ co ‐ethylene)‐type oligomers, cooperatively catalyzed by organocatalysts and Brønsted acids was investigated. Thus, we successfully obtained oligomers that contain a substantial amount of 1,3‐hydroxy groups in the main chain. This conceptually new approach is an important step towards realizing the one‐step synthesis of poly(vinyl alcohol)s from acetaldehyde with perfect atom economy.
