A study was designed to show the nature of weathering of an elastomer poly(ester‐urethane), and to indicate methods of overcoming the deficiency. Unprotected polymer, when exposed to UV radiation in a Weatherometer, showed deterioration which is characterized by loss of tensile strength, some increase in modulus, and a decreased extensibility of surface skin.
