The effect of reprocessing on the structural order of a poly(vinyl chloride) compound is studied using differential scanning calorimetry (d.s.c.). Reprocessing was simulated in the d.s.c, instrument by subjecting the polymer to multiple heating sequences leading to various maximum temperatures. The traces of the processed material contain information about its previous processing history. The development of a network of entanglements and of primary and more recent order re-formed in each of the cooling sequences is postulated.
