Abstract:

Thermally stable high performance polyimides, poly(arylene ether), and poly(arylene sulfide) systems containing aryl phosphine oxide comonomers in controlled concentrations have been prepared and characterized. In general, tough thermoplastic materials have been produced that show significant char yield in air, which increase with the concentration of aryl phosphine oxide. Thus, they are considered candidates for fire safe thermoplastic materials. Preliminary cone calorimetry measurements have been conducted on lower performance aliphatic polyamides, which indicate that, indeed, the heat of combustion is reduced. Additional characterization studies are in progress and will be discussed at the meeting.
