Chemical route to polyurethane polymer Utilized in creation of spandex. Spandex is especially made up of a polyurea derived within the response of the diol and a diisocyanate. Two classes of spandex are defined through the "macrodiols". A single class of macrodiols would be the oligomer developed from tetrahydrofuran (i.
The initial spandex fibers were being developed on an experimental stage by on the list of early pioneers in polymer chemistry, Farben fabriken Bayer. He gained a German patent for his synthesis in 1952.
