Abstract EN
Tow organophosphate compounds namely triallyl phosphate (I) and Triphenyl phosphate (II) were prepared .
The compound (I) was polymerized (addition polymerization) by adding ethyl methyl keton peroxide and Cobalt octate as accelerator to obtain triallyl phosphate resin (III) .
The compound (II) was polymerized (condensation polymerization) by adding paraformaldehyde to obtain Triphenyl phosphate formaldehyde resin (IV) .
These compounds were identified by elemental analysis , calculation of the percentage of phosphorus by gravimetric methods and infrared spectroscopy .
Some new interpenetrating polymer networks (IPNs) based on the prepared organophosphate resins and epoxy resin (5-25 %w/w) were prepared .
Mechanical properties such as impact strength and hardness for these IPNs were studied and it was found the impact strength was increased with increasin g the content of organophosphate resins in the epoxy resin network while the hardness was decreased in comparison with epoxy resin alone because of the flexibility properties for organophosphate resins.
Moreover , thermal stability of the IPNs was evaluated by thermogravimetric analysis (TGA) .
From some thermal stability parameters measured such as decomposition temperature , rate of decomposition , activation energy and char content , it was observed that the organophosphate resins were improved the thermal stability of the epoxy resin network .
Furthermore , flame resistance of these IPNs was investigated according to ASTM 568 .
The results were indicated that the organophosphate resins increase flame resistance for the prepared polymeric networks by decreasing the rate of burning and weight loss .
