Abstract
U ovom radu istražen je utjecaj dodatka ekstrakta ružmarina (ER) na toplinsku i termooksidacijsku stabilnost polimerne matrice polietilena (PE) i polipropilena (PP) . Toplinska razgradnja polietilena i polipropilena se odvija kroz jedan stupanj, dok se njihovi kompoziti PE/ER i PP/ER razgrađuju u dva stupnja. Toplinska i termooksidacijska razgradnja ekstrakta ružmarina se odvija kroz tri stupnja. Toplinska postojanost kompozita PE/ER se poboljšava dodatkom ekstrakta, dok u slučaju kompozita PP/ER ekstrakt ne utječe na toplinsku postojanost polimerne matrice polipropilena. U struji kisika čisti polietilen i kompozit PE/ER se razgrađuju u tri područja razgradnje. Termooksidacijska razgradnja čistog polipropilena i kompozita PP/ER se odvija u dva stupnja. Dodatak ekstrakta ružmarina poboljšava termooksidacijsku postojanost obiju istraživanih polimernih matrica, odnosno kompozita, pri čemu je vidljiv značajniji utjecaj na polimernu matricu polietilena.
Abstract (english)
In this work the influence of the addition of rosemary extract (RE) on the thermal and thermooxidative stability of the polymer matrix of polyethylene (PE) and polypropylene (PP) were investigated. Thermal degradation of the polyethylene and polypropylene occurs in a single degradation step while their composites PE/ER and PP/ER decompose in two steps. Thermal and thermooxidative degradation of rosemary extract takes place through three steps. The thermal stability of the PE/ER composite is improved by the addition of the extract, while in the case of the PP/ER composite the extract does not affect the thermal stability of the polypropylene polymer matrix. In the oxygen atmosphere pure polyethylene and PE/ER composite are degraded in three areas of decomposition. Thermooxidative decomposition of pure polypropylene and PP/ER composite takes place in two steps. The addition of rosemary extract improves the thermooxidative stability of both composites, while having a more significant effect on the polyethylene polymer matrix
