Results and discussion

Any other information on results incl. tables

Heating a commercially polycarbonate specimen as powder (extremely high surface) 
showed weight loss beginning at 420 °C, whereas a commercially  polyphenylene 
specimen as powder showed weight loss beginning at 190 °C.  Injection molding 
temperatures for polycarbonate polymers are between 249  to 315 °C.
GC/MS analysis of vapours resulting from heating the polycarbonat powder and the polyphenylene powder to 250 °C yielded weight loss of 1 % and 8 % resp. and weight fractions of 0.05 % TPP and 3.6 % TPP resp. refering to the loss in weight.

Applicant's summary and conclusion

A method is described for determing TPP released from thermally stressed polymers. However, the test conditions are unrealistic compared to normal use conditions
