Abstract: [cze] [eng]
Teoretická časť diplomovej práce je venovaná funkcionalizácii polyolefínov s cieľom urýchlenia ich degradácie a zvýšenia obsahu uhlíka z obnoviteľných zdrojov so zameraním na hydroxykyseliny. Experimentálna časť je zameraná na prípravu vzorkou a štúdium vlastností takto pripravených zmesí polypropylénu a polyethylénu s kyselinou polymliečnou s rôznym obsahom iniciátoru a maleinanhydridu. Vzorky boli hodnotené pomocou stanovenia stupňa konverzie maleinanhydridu, diferenčnej skenovacej kalorimetrie, infračervenej spektroskopie, indexu toku taveniny a mechanických vlastností. The theoretical part of the diploma thesis is focused on the funcionalization of polyolefins in order to accelerate their degradation and to increase their carbon content from renewable resources with focus on hydroxyacids. The experimental part is focused on preparing samples and studying the properties of the polypropylene and polyethylene blends with the polylactide with different contents of the initiator and the maleic anhydride. Samples were evaluated by determining the degree of conversion maleic anhydride, differential scanning calorimetry, infrared spectroscopy, melt flow index and mechanical properties.
