20.500.12556/RUL-95542 Določitev temperatur faznih prehodov polieterimida, polisulfona ter polietersulfona Determination of temperature phase transitions for polyetherimide, polysulphone and polyethersulphone Cilj zaključne naloge je bil določiti temperaturo steklastega prehoda (Tg) ter temperaturo degradacije (Tdeg) za tri amorfne polimerne materiale, to so polieterimid (PEI), polietersulfon (PESU) in polisulfon (PSU). Meritve so bile opravljene z DSC postopkom na 10 vzorcih za vsak izbran material in temperaturo faznega prehoda. Tg za material PSU je 189,602±0,837°C, za material PEI 219,392±1,358°C ter za material PESU 226,455±0,527°C. Najnižji Tg ima torej material PSU, nato PEI in potem PESU. Tdeg za material PESU je 496,919±8,630°C, za material PEI 521,334±2,971°C ter za material PSU 527,565±3,975°C. Najnižji Tdeg ima material PESU, nato PEI in potem PSU, kar je ravno obratno kot pri Tg. The goal of the thesis was to determine glass transition temperature (Tg) and the degradation temperature (Tdeg) for three amorphous materials, i.e. polyetherimide, polyethersulphone and polysulphone. Glass transition temperatures and degradation temperatures were measured with DSC technique. For each material and phase transition temperature we prepared 10 samples, on which we performed the measurements. Tg for material PSU is 189,602 ± 0,837°C, for PEI 219,392 ± 1,358°C and for PESU 226,455 ± 0,527°C. The lowest Tg has a PSU material, then PEI and then PESU. Tdeg for material PESU 496,919 ± 8,630°C, for PEI 521,334 ± 2,971°C and for PSU 527,565 ± 3,975°C.
