Description

Thermal degradation of blends of Poly (vinyl chloride) /Polyurethane (PVC/PU) was examined by thermogravimetry, differential thermal analyis, ultraviolet-visible spectroscopy, measurement of gel content and chemiluminescence analysis. The results obtained were as follows : Thermal degradation of the blends started at lower temperatures than that of each homopolymer. Polyene formation of PVC caused by HCI elimination reaction and successive gel formation by crosslinking reaction were accelerated by the blend of PU, and maximum effect was observed at 1 I blend ratio (wt) Relative amount of chemiluminescence of PU due to thermal oxidation was reduced remarkably by the blend of PVC. Thus, thermal degradation of the each component polymer in the blends was accelerated by the other component.
