Abstract
A halogen-free, phosphorus-free poly-cyclic compound is used a flame retardant. This compound has amide and hydroxy groups, and thus it is able to react with an epoxy resin to form a reactive type flame-retardant advanced epoxy resin. The advanced epoxy resin together with an inorganic additive are mixed with an epoxy resin to form a halogen-free, phosphorus-free flame-retardant epoxy composition, which can be used in the manufacture of a printed circuit board and as an encapsulation material for a semi-conductor device.
