<p>Epoxy resins reacted with an oxirane group containing phosphonate of formula I, wherein R is hydrogen or lower alkyl and R1 is a lower alkyl. The backbone of the epoxy resin contains a functional substituent which reacts with (I) preferably a hydroxyl substituent. The cured epoxy resins reacted with the phosphonate (I) have improved flame resistance or glass temperatures.</p> |
