摘要：

This paper presents the influence of the processing temperatures on the physical mechanical properties of polyoxymethylenes (POM) used in injection molding of high performance sport products. The test-pieces were obtained by processing POM at the following temperatures: 180 degrees C, 190 degrees C, 200 degrees C, 210 degrees C, 220 degrees C, 230 degrees C and 240 degrees C. It was established that the pressure in the mold decreases as the processing temperature increases. Further, thermal analyses (TG, DSC and DMA) were performed and it was noticed that the processing temperature had an influence on the thermal stability of the polymer, but the vitrification temperatures (T-u) and the melt temperatures (T-t) were poorly influenced by the processing temperature.
