摘要:

AbstractA study was designed to show the nature of weathering of an elastomer poly( ester‐urethane), and to indicate methods of overcoining 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 ski
