Abstract
This invention relates to an epoxy resin composition, in particular a curable phosphorus containing flame retardant epoxy resin composition comprising epoxy resin and an epoxy resin chain-extending amount of a diaryl alkylphosphonate and/or diaryl arylphosphonate and a cross-linking agent. The curable flame retardant compositions are useful in e.g., printed wiring boards or molding compounds for electronic applications, protective coatings, adhesives, as well as structural and decorative composite materials.
