Abstract
The thermal degradation of poly(vinyl chloride) (WC) and blends of PVC with polystyrene has been studied using thermogravimetric analysis coupled to F ourier transform infrared spectroscopy. The degradation of WC commences at weak links by an ionic pathway, but there is evidence to suggest the presen ce of a radical pathway at high temperatures. While there is some chemical interaction between WC and polystyrene, the principal mode of stabilization is a physical process.
