Curing ۴,'۴-bis(maleimide)diphenylmethane resin with Solution aliphaticamines and triallyl cyanurate

In this article, BMI resin is extended by nucleophilic addition reaction with aliphatic diaminesdiethylenetriamine (DETA) and triethylenetetramine (TETA). Increasing the concentration ofaliphatic methylene amines leads to a slight decrease in the starting temperature of baking around ۶°C. The heat of polymerization significantly decreased with chain extension with diamines. Furtherreduction of ΔH is achieved by adding triallyl cyanurate (TAC) to the extended chain of BMI. Thethermal stability of the cured resin at ۱۸۰ °C in nitrogen atmosphere is independent of theconcentration of methylene diamines used for chain extension.
