More than 50 years after Otto Bayer's detailed description of [ m , n ]‐polyurethanes, the first general synthesis of [ n ]‐polyurethanes 1 is described. This series of aliphatic [ n ]‐polyurethanes is synthesized by the in situ polymerization of the corresponding α , ω ‐isocyanato alcohol monomers, which in turn are made out of linear α , ω ‐amino alcohols and di‐ tert ‐butyltricarbonate. Polymers of high molecular weight possessing a uniform microstructure are obtained, while their melting points show a strong odd–even effect.
