Polymeric materials are increasingly used in areas where fire safety is critical. These materials are usually based on polymers such as polyamide, polyester, polyurethane, polycorbonate etc. Due to their low flame resistance the application of such polymeric materials is usually subjected to strict fire regulations. Our research is particularly focused on development of new and efficient synthetic routes for compounds based on phosphonamidates and phosphonates. We have also found out that some of these compounds exhibit thermal stabilities greater than 300�C, which makes them very interesting for their application in high temperature processable polymers like PET or polyamide. Additionally they presumably show a very good gas phase flame retardant action which is generally explained by their ability to release PO* and PO2* during combustion. By means of various flammability tests we have also found out that these novel compounds work very well in flame retardancy of polyurethane flexible foams.
