N2 - The present study was inspired by different industry projects in which a strong dependence of the fatigue fracture performance ofPOM on the processing conditions was observed. To examine the relationships under more reproducible conditions, plates of twodifferent POM homopolymer resins (one significantly nucleated) were produced by compression molding and by injection moldingunder moderate conditions. For the injection molding, three different mold temperatures were used. At specific locations, the plateswere analyzed concerning their hierarchical structure on the micro- and nanolevel and concerning their fatigue fractureperformance. For the fatigue fracture performance, the dependence on the processing conditions was rather small for thenucleated resin but much more significant for the other resins. This dependence could not be related to morphological effectsonly, and thus, a combined effect of morphology and residual stresses was assumed.
