Dear Richard,
One reason for A-D strip reaction might be the fact that the softening chemical
in PVC production are esters from phthalic acid that, as the decomposition of the
PVC reaches a certain point, heat and light being the main catalysts,
Brakes the weak chemical bonds that holds the phthalathes in place
and we get an acidic reaction, non odourous as to the characteristics of phthalic acid.
