- 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.
