Polyurethanes (PUs) can be given as one of the most popular polar polymers. The PUs are usually composed of soft segment formed with polymer glycol and hard segment done with diisocyanate and chain extender. History, basic chemistry of isocyanates, preparation method, chemical and physical structures of polyurethanes were described to understand properties of polyurethanes.
