The objective of this work is the investigation of the thermal degradation of nitrogen-containing polymeric materials (polyamides, polyurethanes and copolymers of the acrylonitrile). The online release of the evolved products could be pursued in dependency of the temperature through the hyphenated methods of the Thermal Analysis (TA-MS, TA-FTIR). The emissions of two incinerators (BIS and VCI) were investigated and identified and quantified by means of the off-line analysis (GC-MS). The finding of degradation pathways was enabled by means of combining the different techniques.El objetivo de la presente tesis es la investigacion de la degradacion termica de los polimeros nitrogenados (poliamidas, poliuretanos y los copolimeros del acrilonitrilo). Con ayuda de los metodos compuestos del Analisis Termico (TA-MS y TA-FTIR) fue posible el observar el desarrollo de las emisiones volatiles de los materiales investigados. Los gases de combustion de dos distintos hornos de incineracion (BIS y VCI) fueron analizadas offline via GC-MS. Las substancias fueron identificadas y cuantificadas. Mediante el empleo simultaneo de las diversas tecnicas analiticas fue posible el descifrar los diversos mecanismos de degradacion de los polimeros nitrogenados estudiados
