Statement of Problem
Thermally-induced degradation of vinylidene chloride copolymers has resulted in considerable losses of polymer material during the production process. The homolysis of the C – Cl bond set up a conjugated polyene sequence, which resulted in the coloration of the copolymers, thereby making them unsuitable for use as films or inhibiting their use as barrier films in packaging applications for food and pharmaceuticals (The Dow Chemical Company, 2005). A second and more serious consequence of the degradation is the evolution of hydrogen chloride which reacts with the walls of process equipment, commonly stainless steel, at process temperatures, to form iron (III) chloride, a strong Lewis acid catalyst which can enhance the dehydrohalogenation process. Thus these two problems, namely, thermal dehydrochlorination of PVDC copolymers at process temperatures (a production problem) and the degradation of production equipment by the resulting product of dehydrochlorination would need to be solved, using suitable comonomers and / or appropriate additives
