The synthesis of the phosphazene trimers, [P(OPh)2N]3 and [P(OCH2CF3)2N]3 were performed successfully. Also, the polyphosphazenes, [PCl2N]n, [P(OPh)2N]n and [P(OCH2CF3)2N]n, were synthesized successfully. The syntheses of the trimeric phosphazenes were investigated first to learn the chemistry and behavior of the polymers. Improvements to trimeric yields were reported, due to procedure modifications. Polymeric macromolecular substitution was sucessfully formed on [P(OPh)2N]n when starting with a cross-linked [PCl2N]n.
The synthesis of an Interpenetrating Polymer Network (IPN) involving polypropylene and [PCl2N]n was inconclusive. The data suggest an apparent IPN appears to have been formed; whereas, the [PCl2N]3 is acting as a plasticizer for polypropylene.
