Abstract
Polyurethanes are one of the most important classes of polymers having a variety of applications in different industries. Importance of thermal degradation study of polyurethanes, understanding occurring processes during thermal stress and also influential parameters on thermal stability of this material offer polyurethanes ability of being applicant in specific conditions. In this article, influence of different structural parameters, methods of improving thermal stability of polyurethanes such as synthesis of polyurethanes with high thermal stability in addition to investigating other methods like synthesis of polyurethane with s-triazine ring, aromatic ring or azomethane linkages, using hyper branched polyols such as crosslinking agents are investigated. Improving thermal stability with the formation of hybrids and methods of increasing flame retardancy of polyurethanes are also other subjects that are investigated in the present article. Finally, analyses that are related to thermal stability and flame retardant are presented.
