Fatigue properties of an ionomer (partially sulphonated polystyrene, S-SSA) were studied and compared with those of parent polystyrene. Data acquired so far suggest that the fatigue lifetime of polystyrene is increased by one or more decades upon introducing 2. 8 mol% of ions into polystyrene. The enhanced fatigue response is considered to arise from an increased resistance to crack propagation provided by presence of ionic aggregates.
