Abstract
U ovom radu ispitan je utjecaj dodatka kompatibilizatora PEGMA mješavinama PE/PA na toplinska svojstva i stabilnost. Nekompatibilizirane PE/PA i kompatibilizirane PE/PA/PEGMA mješavine pripremljene su u Brabender gnjetilici i hidrauličkoj preši postupkom iz taline. Toplinska svojstva čistih polimera polietilena (PE), poliamida (PA), kompatibilizatora PEGMA, nekompatibiliziranih PE/PA i kompatibiliziranih PE/PA/PEGMA mješavina istražena su primjenom diferencijalne pretražne kalorimetrije (DSC), a toplinska stabilnost određena je primjenom termogravimetrijske analize (TGA). Rezultati DSC analize pokazali su kako miješanje polimera PE i PA u različitim omjerima kao i dodatak kompatibilizatora ne utječe znatno na talište i kristalište PE i PA faze, te nemaju značajan utjecaj na kristalnost PE u mješavinama. Međutim, rezultati pokazuju da prisutnost PE ograničava kristalizaciju PA, posebno uzoraka sa 60% i 80% PE. TGA analizom utvrđeno je da miješanjem polimera PE i PA u različitim omjerima te dodatkom kompatibilizatora PEGMA dolazi do povećanja vrijednosti temperature početka razgradnje poliamida što upućuje na pozitivan učinak kompatibilizatora na toplinsku stabilnost mješavina.
Abstract (english)
In this paper, the effect of addition of compatibilizer PEGMA to PE/PA blends on thermal properties and stability were investigated. Non-compatibilized PE/PA and compatibilized PE/PA/PEGMA blends were prepared in a Brabender kneader and hydraulic press using melt process. The thermal properties of pure polyethylene (PE), polyamide (PA), compatibilizer PEGMA, non-compatibilized PE/PA and compatibilized PE/PA/PEGMA blends were investigated using differential scanning calorimetry (DSC), and thermal stability was determined using thermogravimetric analysis (TGA). The results of the DSC analysis showed that the mixing of PE and PA polymers in different proportions as well as the addition of compatibilizers do not significantly affect the melting point and crystallinity of the PE and PA phases, and do not have a significant impact on the crystallinity of PE in the blends. However, the results show that the presence of PE limits the crystallization of PA, especially the samples with 60% and 80% PE. By TGA analysis, it was determined that by mixing PE and PA polymers in different proportions and by adding the PEGMA compatibilizer, the value of the temperature at which the polyamide begins to decompose increases, which indicates a positive effect of the compatibilizer on the thermal stability of the mixtures.
