Abstract
Modifikacija polilaktidne kiseline (PLA) provedena je dodatkom natrijevog alginata (NaAlg) s ciljem određivanja njegovog utjecaja na toplinska svojstva i kristalnost PLA. Uspješno su pronađeni optimalni uvjeti za predmiješanje početnih polimera kao i uvjeti ekstrudiranja na dvopužnom ekstruderu s kontrarotirajućim vijcima. Diferencijalna pretražna kalorimetrija (DSC) je primijenjena u svrhu istraživanja utjecaja NaAlg na toplinska svojstva i kristalnost PLA. Utvrđena je mješljivost mješavine PLA/NaAlg u istraživanom području sastava, te djelovanje NaAlg kao nukleacijskog agensa PLA. Prema istraživanju optimalan udio NaAlg je 2 mas.%.
Abstract (english)
The modification of polylactide acid (PLA) was carried out by the addition of sodium alginate (NaAlg) with the aim of determining its influence on the thermal properties and crystallinity of PLA. Optimal conditions for premixing the initial polymers as well as extrusion conditions on a twin-screw extruder with counter-rotating screws were successfully found. Differential scanning calorimetry (DSC) was applied to investigate the effect of NaAlg on the thermal properties and crystallinity of PLA. The miscibility of the PLA/NaAlg blend in the investigated composition range, and the action of NaAlg as a nucleating agent of PLA, were determined. According to the research, the optimal proportion of NaAlg is 2 wt %.
