This diploma thesis deals with chemical recyclation polylactide to lactide. In the theory is summarized actual state of knowledge about chemical recyclation of polylactides, their properties, preparations a possibilities of characterization. Experimental part of work verify ethanolysis of PLA withthe samples of granulate, waste filaments and textiles. In the experimental work is suggested an optimalization of alcoholysis to direct yield of oligomer suitable for depolymerization to lactide. This method was verified for 5 different samples of PLA, which 4 of them was made of waste PLA. The time needed for depolymerization was evaluated and the effect of catalysis. Lactide and PLA recyclates was further analyzed by NMR, FTIR, DSC and GPC.
