Abstract: [slo] [eng]
Diplomová práca sa zaoberá prípravou polypropylénu funkcionalizovaného maleimidmi, založenou na reakcii medzi maleínanhydridom a amínom. Prehľad funkcionalizácie polypropylénu maleínanhydridom reaktívnou extrúziou a možnosti syntézy a využitia maleimidov sú obsiahnuté v teoretickej časti. Reaktívnou extrúziou boli pripravené vzorky polypropylénu funkcionalizovaného maleimidmi, pričom použité boli nízkomolekulárne amíny (anilín a 4-aminofenol) a vysokomolekulárne polyétermonoamíny. Funkcionalizované vzorky polypropylénu boli pripravené viacerými metódami, líšiacimi sa zložením reakčnej zmesi a prevedením reakcie očkovania. Z nízkomolekulárnych amínov boli syntetizované príslušné maleamové kyseliny a maleimidy, ktoré boli ďalej použité na funkcionalizáciu polypropylénu. Pre charakterizáciu vzoriek bol stanovený stupeň konverzie monoméru a index toku taveniny a prevedené boli analýzy infračervenou spektroskopiou s Fourierovou transformáciou, diferenčnou kompenzačnou kalorimetriou a termogravimetrickou analýzou. Syntéza nízkomolekulárnych látok bola ďalej sledovaná chromatografiou na tenkej vrstve a termogravimetrickou analýzou s analýzou uvoľnených plynov. Diploma thesis deals with preparation of polypropylene functionalized by maleimides, based on the reaction between maleic anhydride and amine. The overview of functionalization of polypropylene by maleic anhydride by reactive extrusion and routes for the synthesis and utilization of maleimides are contained in the theoretical part. Samples of maleimide-functionalized polypropylene were prepared by reactive extrusion using low molecular weight amines (aniline and 4-aminophenol) and hight molecular weight polyether monoamines. Functionalized polypropylene samples were prepared by several methods differing in the composition of the reaction mixture and performing a grafting reaction. Appropriate maleamic acids and maleimides were synthesized from low molecular weight amines and further used to functionalize the polypropylene. To characterize the samples, the degree of monomer conversion and melt flow index were determined and further analyses were performed by Fourier transform infrared spectroscopy, differential scanning calorimetry and thermogravimetric analysis. The synthesis of low molecular weight products was further monitored by thin layer chromatography and thermogravimetric analysis with evolved gas analysis.
