Effect of silicon and phosphorus on the degradation of polyurethanes

“…Siliconated PU shows great improvement in acid/base and solvent resistance 12 and excellent thermal stability and mechanical properties. 13,14 The flammability of polymers on fire exposure may be achieved by employing additive-type stabilizers and flame retardants or by improving its structure. 15,16 The flame retardancy of siliconated polymer can be enhanced [17][18][19] and the incorporation of a silicone moiety into the structure of polyimide increases its thermal stability.…”
