The influence of structure formation on thermodegradation of poly(vinyl chl
oride) (PVC) in complex polymer objects is considered in the article. It wa
s shown that structural-physical states of polymer mixtures depend on the m
ethod of obtaining a composite and affinity of the polymers. Composites of
the same composition may be obtained, which possess rather different dehydr
ochlorination rates for PVC. (C) 1999 John Wiley & Sons, Inc.
