Radiation Chemistry of Polyvinyl Chloride
The irradiation, with high-energy electrons, of the polyvinyl chloride structure, - CH2CH(C1) - was studied. Radiation yields for HCl were determined as a function of temperature. Post-irradiation changes in vacuo and in air, were measured by electron paramagnetic resonance and by visual observation of color. It is concluded that the major primary chemical processes are the formation of -CH2CH- + Cl. and - CH=CH- + HCl. A free-radical chain dehydrochlortnation, involving the unstable -CHCH(C1) - radical, appears to explain the development of conjugated unsaturation. The radiation yield for HC1 increases with temperature from a minimum value of G = 5.6 at -90°C and below, to G = 23 at 70°C.
