In the present paper, we study the effect of both morphology and
compatibilization on the reaction to fire of blends of recycled
poly(ethylene terephthalate) (PET) with recycled polycarbonate (PC).
The Actual measurment of melt viscosity at a large number of
temperatures and shear rates is frequently a tedious and time
consuming task. The experimental validity for superimposing Log.
shear stress - Log shear rate curves at different temperatures along
the Log shear rate axis has been established for polycarbonate.
