Abstract:
This project has investigated the incorporation of
either triphenyl phosphine oxide or diphenyl methyl
phosphine oxide moieties into the chain. The basis for
these studies was the anticipation that the phosphorus
would enhance the fire resistance of thermoplastic and
thermosetting materials, without the potential hazard of
extraction or vaporization that are common for many fire
retardant additives. An additional driving force was
the expectation that the mechanical properties of such
aryl phosphine oxide modified polymers would be
interesting and maintained, independent of their
concentration. The latter is not true for the physical
additives that are normally observed to embrittle
ductible engineering thermoplastics if employed beyond a
certain concentration level. This new concept has been
successfully explored synthetically for a wide variety
of macromolecular materials including polyesters,
polyamides, polyarylene ethers, polimides, and epoxy
resin networks cured with aromatic phosphorous
containing diamines.
