Abstract
The electrical and physical properties of unstabilised and stabilised poly(vinyl chloride) (PVC) have been measured before and after ultraviolet irradiation. The results showed that the percentage changes in properties can be correlated with the structure of stabiliser added to the polymer.

Radiation effects on the formation of conjugated double bonds in the thermal degradation of poly(vinyl chloride) (PVC) and poly(vinyl alcohol) (PVA) were investigated.

Stress relaxation modulus data, E,(t), have been determined between -70 and + 170Β°C on blends of three samples of poly(viny1 chloride) of different molecular weights with di-2-ethylhexyl adipate, di-2-ethylhexyl phthalate, epoxidiaed soybean oil, and a poly(propy1 adipate), respectively. The relaxat
