Abstract

A new reactive phosphorus-containing curing agent with imine linkage called 4,4'-[1, 3-phenyl-bis(9, 10-dihydro-9oxa-10-phosphaphenanthrene-10-yl)dimethyneimino)] diphenol (2) was synthesized both via two-pot and one-pot procedure. The chemical structure of this curing agent was confirmed by FTIR, ¹H, [sup.31]C, and [sup.31]P NMR spectra. A series of thermosetting systems were prepared by using conventional epoxy resins (E51), 4, 4'-diaminodiphenyl methane (DDM) and (2). Resins with different phosphorus contents were obtained by changing the DDM/(2) molar ratios. Their dynamic mechanical thermal, thermal and flame-retardant properties were evaluated by dynamic mechanical thermal analysis (DMTA), thermogravimetric analysis (TGA), and limiting oxygen index (LOI), respectively. All samples had a single [T.sub.g] which showed that these epoxy resins were homogeneous phase. Both the two char yields under nitrogen and air atmospheres increased with increasing content of (2) and the LOI values increased from 24.5 for standard resin to 37.5 for phosphorus-containing resin, which indicated that incorporation of (2) could impart good thermal stability and excellent flame retardancy to the conventional epoxy thermosets., INTRODUCTION Epoxy resins have widely used in the fields of coatings, paintings, adhesives, composites and so on, owing to their excellent mechanical, adhesive, and electrical properties [1, 2]. However, poor [...]
