## Abstract 10‐Ethyl‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (**1**) can be nitrated using acetic anhydride and fuming nitric acid. The nitro group is reduced using palladium on charcoal and hydrogen. These reaction conditions are used for the synthesis of an analogous DOPO‐based diaminic hardener (*

A novel flame-retardant epoxy resin, (4-diethoxyphosphoryloxyphenoxy)(4glycidoxyphenoxy)cyclotriphosphazene (PPCTP), was prepared by the reaction of epichlorohydrin with (4-diethoxyphosphoryloxyphenoxy)(4-hydroxyphenoxy)cyclotriphosphazene and was characterized by Fourier transform infrared, 31 P NM
## Abstract A fire retardant phosphorous‐containing bisphenol compound, bis(3‐diethyl phosphono‐4‐hydroxyphenyl)‐sulfide (DPHS), has been inserted in an epoxy network. In particular, a chain extension procedure has been used to incorporate DPHS into a standard bisphenol epoxy resin. Different amine
China ## SYNOPSIS A new phosphorus-containing oxirane, bis-(3-glycidyloxy) phenylphosphine oxide (BGPPO), was synthesized. Further curing BGPPO with diamine curing agents, dicyanodiamide (DICY), 4,4'-diaminodiphenylmethane (DDM), and 4,4'-diaminodiphenylsulfone (DDS), respectively, resulted in se
