The low cost and excellent performance of poly(vinyl chloride)
(PVC) make it a very attractive and suitable plastic for a wide
variety of applications. With respect to the production and
consumption of synthetic materials, it stands third in the world
after polyethylene and polypropylene. However, PVC suffers from
poor thermal and light stability. It undergoes rapid autocatalytic
dehydrochlorination upon exposure to heat and light during its
molding and use, respectively. As a result, conjugated polyene
sequences are formed from the beginning of the reaction, and they
give rise to discoloration of the polymer and seriously change its
physical properties. Degradation also causes a drastic change in
the mechanical properties of the polymer, which is accompanied by a
decrease or increase in its average molecular weight as a result of
either chain scission or crosslinking of the polymer molecules,
respectively.
