Abstract
Phosphorus-containing benzoxazine-based bisphenols and derivatives thereof are disclosed. The phosphorus-containing benzoxazine-based bisphenols are prepared by reacting DOPO with benzoxazine to form the phosphorus-containing benzoxazine-based bisphenols. The phosphorus-containing benzoxazine-based bisphenols can further to form advanced epoxy resins. The advanced epoxy resins can further be cured to form flame retardant epoxy thermosets.
