In 1937 the doctor Otto Bayer was looking for a new road for sintetizar fibres that, after the invention of the nylon, had increased the demand of synthetic fibres to substitute to the silk. With 35 years of age, to the then boss of the main scientific laboratory of the designated I.G. Farbenindustrie In Leverkusen (Germany), no only interested him develop a new chemical but it also pretended to achieve a method of production of plastics simpler and with fewer by-products.

His invention of the chemicals of the poliuretano (PUR), based in the reaction of diisocianatos and polioles, implanted no without effort: the idea of sintetizar plastic from the isocianatos, known by his high reactivity and chemical unsteadiness, was not very received by his upper. In spite of this, on 13 November 1937 requested a patent on the results of the investigation and can consider that the German imperial patent DRP 728.981 constitutes the game of birth of the chemicals of the poliuretano.
