Azides are known as a class of organic compounds that are very reactive, amongst others towards alkenes and alkanes. At elevated temperatures the azide-group decomposes, releasing a nitrogen molecule and creating a highly reactive nitrene species, which is able to react with fully saturated hydrocarbon polymer chains. In the present study the properties of four different azide functionalities are investigated: alkyl azides: R-N(3); aryl azides: R-C(6)H(4)-N(3); sulfonyl azides: R-SO(2)-N(3); and azidoformates: R-O-C(O)-N(3). The aim of the study is to determine and compare the properties of different types of azide functionalities and their ability to react with saturated EPM-rubber. Several di-azide compounds are tested with respect to their cross-linking efficiency for EPM. An overview of synthetic routes towards different azide types is given as well.
