Epoxy resin, curing agent and 9,10-Dihydro-9-oxa-10-phosphaphenanthrene derivative

摘要

The invention discloses a novel cross-linked epoxy resin with flame-retardant properties and method for producing the same. The polymeric material of the invention includes an epoxy resin, a curing agent and a modification agent. Particularly, the modification agent is a derivative of 9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-Oxide (DOPO). Moreover, the curing agent is 4,4′-diaminodiphenyl methane (DDM), or tris(4-aminephenyl)amine (NNH).
