Abstract (AI)
The discovery of polyurethane [PU] dates back to the year 1937 by Otto Bayer and his coworkers at the laboratories of I.G. Farben in Leverkusen, Germany. The initial works focussed on PU products obtained from aliphatic diisocyanate and diamine forming polyurea, till the interesting properties of PU obtained from an aliphatic diisocyanate and glycol, were realized. Polyisocyanates became commercially available in the year 1952, soon after the commercial scale production of PU was witnessed (after World War II) from toluene diisocyanate (TDI) and polyester polyols. In the years that followed (1952-1954), different polyester-polyisocyanate systems were developed by Bayer.
Key Findings
1
Between 1952 and 1954, Bayer developed multiple polyester–polyisocyanate systems, including systems based on toluene diisocyanate and polyester polyols.
2
Commercially available polyisocyanates emerged in 1952, enabling large-scale polyurethane production after World War II.
3
Early polyurethane research focused on products formed from aliphatic diisocyanates and diamines, producing polyureas.
4
Polyurethane was discovered in 1937 by Otto Bayer and coworkers at I.G. Farben in Leverkusen, Germany.
5
The notable properties of polyurethane produced from aliphatic diisocyanates and glycols motivated further development.
