| Abstract: | ![]()
Poliam BS-5 (the product of reaction between aniline and formaldehyde) is studied as concerns its use as a hardener of ED-22, UP-643, and ED-BM epoxy resins. Serving as a curing agent, it possesses high reactivity, while the thermal-mechanical and physicomechanical properties of the cured polymers are at a level corresponding to the characteristics of polymers with application of known curing agents such as the aromatic diamines 4,4'-diaminodiphenylmethane and 4,4'-diaminodiphenylsulfone and eutectic mixtures with metaphenylene diamine. |
