Abstract
Abstract A heat-resistant flame-retardant epoxy resin composition comprises a halogen-containing epoxy resin obtained by reacting a trifunctional epoxy compound of formula (I) wherein R 1 and R 2 are the same or different and each is hydrogen, alkyl of 1 to 12 carbon atoms, aryl or cycloalkyl of 3 to 6 carbon atoms, R 3 is hydrogen or alkyl of 1 to 10 carbon atoms, Z is a group of formula (II): in which A is hydrogen or methyl, Y is a group of formula (III) or (IV): in which R 4 , R 5 , R 6 and R 7 are the same or different and each is hydrogen or alkyl of 1 to 4 carbon atoms, and n is 0 or 1, with a halogenated bisphenol in the present of a catalyst.
