Abstract
U ovome radu ispitan je utjecaj kompatibilizatora poli(etilen-g-maleinskog anhidrida) (PE-g-MA) na toplinska svojstva i stabilnost mješavina polietilena (PE) i otpadnog poliamidnog praha (PA). Uzorci su pripremljeni umješavanjem na Brabender gnjetilici i prešanjem na hidrauličkoj preši. Toplinska svojstva polimera u ovom radu određivana su pomoću tehnike diferencijalne pretražne kalorimetrije (DSC) i dinamičko mehaničke analize (DMA), a toplinska stabilnost pomoću termogravimetrijske analize (TGA). Rezultati DSC analize pokazali su kako miješanje polimera PE i PA u različitim omjerima kao ni dodatak kompatibilizatora ne utječu znatno na talište i kristalište PE i PA faze u mješavinama. Također, prisutnost PE otežava stvaranje kristalne faze PA u mješavinama bez i s kompatiblizatorom. TGA analizom utvrđeno je da je početak gubitka mase u kompatibliziranim mješavinama pomkanut na niže temperature u odnosu na odgovarajuće mješavine bez kompatibilizatora što upućuje na to da ne dolazi do povećane interakcije između komponenata mješavina koju promiče kompatibilizator. Uspoređujući rezultate DMA analize mješavina bez i s kompatibilizatorom nije vidljiva veća razlika, odnosno kompatibilizator PE-g-MA ne pospješuje mješljivost PE i PA.
Abstract (english)
In this thesis, the influence of compatibilizer PE-g-MA on thermal proporties and stability of polyethylene (PE) and waste polyamide powder (PA) blends were investigated. Samples were prepared by mixing in a Brabender kneader and pressing with a hydraulic press. The thermal properties of polymers were investigated using differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) 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 compatibilizer do not significantly affect the melting point and crystallinity of the PE and PA phases. Also, the presence of PE limits the crystallization of PA in blends without and with compatiblizer. TGA analysis determined that the onset of mass loss in compatibilized blends was shifted to lower temperatures compared to the corresponding blends without compatibilizer, indicating that there is no increased interaction between the blend components promoted by the compatibilizer. Comparing the results of the DMA analysis of blends without and with a compatibilizer, no significant difference is observed, meaning that the PE-g-MA compatibilizer does not enhance the miscibility of PE and PA.
