Abstract:Veliko izdelkov iz plastične mase danes konča na odlagališčih. Kemijsko recikliranje je postopek, s katerim se želimo temu izogniti. Poliamid 6.6 smo reciklirali s postopkom hidrolize v nevtralnem in bazičnem mediju. Kot rezultat kemijskega recikliranja poliamida 6.6 smo želeli dobiti monomerne enote čim višje čistosti, zato smo v posamezen eksperiment vnašali čim manj kemikalij. Rezultate depolimerizacije smo spremljali z IR, RAMAN in 1H NMR spektroskopijo, kakor tudi z DSC analizo. Beležili smo tudi pH tekočega ostanka in maso trdnega ostanka. Opravljene analize so potrdile, da nam je uspelo vlakno PA 6.6 razgraditi na manjše oligomerne in tudi monomerne enote.
Keywords:Poliamid 6.6, recikliranje, hidroliza, IR spektroskopija, Raman spektroskopija, DSC termična analiza.

Title:Analysis of degradation products of chemical recycling of polyamide 66
Abstract:Today many plastic materials ends up in landfills. With the process of chemical recycling we want to avoid this situation. Polyamide 6.6 was recycled by the process of hydrolysis in neutral and alkaline media. As a result of the chemical recycling of polyamide 6.6, we want to acquire purity of the monomeric units as high as possible, therefore we minimized the use of chemicals in each experiment. The results of depolymerization was monitored by IR, Raman and 1H NMR spectroscopy, as well as by DSC thermal analysis. We also measured the pH of the liquid phase and the mass of the solid phase. Analytical methods confirmed that we managed to break down PA 6.6 units into smaller oligomeric and also monomeric units.
Keywords:Polyamide 6.6, recycling, hydrolysis, IR spectroscopy, Raman spectroscopy, DSC thermal analysis.
