Flame-retardant waterborne polyurethane has long been studied as a flame-retardant, non-flammable, adhesive material for wood, for example. Since there are already many good review articles and specialized books, this chapter will review only the major studies of new flame-retardant aqueous polyurethanes reported in the last few years. In many cases, there is the synthesis of polymer materials, thermal analysis that proves flame retardancy alone or in combination with other materials, as well as FTIR, NMR, MS for structural confirmation, and SEM for aggregate state confirmation. The study may be carried out by several measurements such as EDX analysis. On the other hand, material flammability tests may include limiting oxygen index, vertical combustion, and cone calorimeter tests. This chapter focuses on methods of analytical measurement of flammability, the purpose of these methods, the correlation between flame retardancy and other structures/physical properties, and related experiments and discussions including composite/special measurements such as TGA-FTIR, and in situ FTIR. Additionally, the authors would like to summarize the relationship between analytical measurements such as thermal measurement with other applications such as macromolecules for photochromic and fluorescence.
