摘要：

Photoageing at lambda > 300 nm (SEPAP, WOM, Xenotest), natural ageing (Bandol) and thermal ageing (100 and 150 degrees C) were performed on ethylene-propylene-diene monomer (EPDM) rubber designed for automotive applications. The thermal ageing study was concentrated on a formulation designed for engine applications (peroxide crosslinked) and photoageing concerned a formulation for outdoor applications (sulfur vulcanized). Analyses were based both on infrared spectroscopy (surface analysis and profile by successive abrasion) and on physical properties analysis (dynamic mechanical thermal analysis (DMTA) and tensile tests). Both methods were complementary to describe the two competitive phenomena involved in ageing of elastomers (oxidation and crosslinking). (C) 2000 Elsevier Science Ltd. All rights reserved.
