“Seventy-five years ago, Dr. Otto Bayer (pictured) was looking for a new synthesis strategy for fibers. He was interested in developing a new chemistry and establishing a more efficient method of producing plastic. His subsequent “invention” of polyurethane chemistry — based on the reaction between diisocyanates and polyols — was not a runaway success from the start. Indeed, the idea of synthesizing plastics from isocyanates, known at the time to be highly reactive and chemically unstable, seemed completely mad to his supervisors. Nonetheless, a patent application was submitted for the research findings on November 13, 1937 and German Imperial Patent (DRP) 728.981 became the “birth certificate” for polyurethane chemistry.”
