Dynamic mechanical thermal properties of moulded poly(vinylchloride) swollen with organic liquids

Compression-moulded unplasticised poly(vinylchloride) (uPVC) was swollen with various organic liquids at two temperatures, 60°C and 30°C, both temperatures being below the glass transition temperature of uPVC. Liquids were chosen to give a range of solubility parameters, molecular sizes and ability to form hydrogen bonds. It was hoped to find a PVC–liquid system which behaved similarly to PVC swollen with vinyl chloride monomer (VCM). [Continues.]
