The release of hydrogen chloride from the thermal decomposition of a sample
of a commercial rigid PVC has been studied in air and nitrogen between 200 and
300C. It is shown that the dehydrochlorination can be represented by a 3/2
order decomposition with activation energies of 36.1 and 41.5 K cals.mole^-1 in
air and nitrogen respectively. The report explains how this kinetic data can
be used to predict the total release of hydrogen chloride as a function of time
from the decomposition of PVC during either isothermal conditions or non-linear
temperature increments as in fires. A comparison is shown between the
experimental and calculated release of hydrogen chloride during a temperature
programmed experiment between 200 and 300C.
