Otto Bayer (4 November 1902 – 1 August 1982) was a German industrial chemist at IG Farben who was head of the research group that in 1937 discovered the polyaddition for the synthesis of polyurethanes out of poly-isocyanate and polyol.
Jun 24, 2024 · Otto Bayer's greatest achievement was ultimately the invention of polyurethane chemistry. The principle of polyaddition using diisocyanates is based on his research, yet at first, his closest colleagues were very skeptical.
Learn how Otto Bayer, a chemist born in 1902, invented polyurethane in 1937 and patented it. Discover how polyurethane became a versatile and indispensable material for various applications, from insulation to furniture, thanks to its adaptability and innovation.

Otto Bayer and co-workers at IG Farben in Leverkusen, Germany, discovered and patented the chemistry of polyurethanes in 1937. Bayer (1902 - 1982) developed the novel polyisocyanate-polyaddition process. The basic idea which he documents from March 26, 1937, relates to spinnable products made of hexane-1,6-diisocyanate (HDI) and hexa-1,6-diamine (H...
Octamethylene diisocyanate and butanediol-1,4 are the units of a polymer produced by Heinrich Rinke. He called this area of polymers "polyurethanes", a name which was soon to become known worldwide for an extremely versatile class of materials. Right from the start, trade names were given to polyurethane products. Igamid® for plastics materials, Pe...
William Edward Hanford and Donald Fletcher Holmes invented a process for making the multipurpose material polyurethane.
In 1969, Bayer exhibited an all-plastic car in Düsseldorf, Germany. Parts of this car, including the body panels, were made using a new process called reaction injection molding (RIM), in which the reactants were mixed and then injected into a mold. The addition of fillers produced reinforced RIM (RRIM), which provided improvements in flexural modu...
