Abstract

The invention discloses a 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-aminophenyl)amine (NNH).

Claims (5)

1. A method for manufacturing a cross-linked epoxy resin comprising the following steps:

(a) preparing a modification agent;

(b) adding a curing agent and the modification agent into an epoxy resin; and

(c) utilizing the result of step (b) under a curing temperature with a curing time to obtain the novel cross-linked epoxy resin,

wherein the modification agent is Dopo-tri-azetidine-2,4-diones.
