2-3 g of finely ground sample powders were placed between Teflon ® sheets and then placed between the platens of a melt press. PVC was melted at 180° C, pressed at 5,000 kPa for 1 minute, and then further pressed at 10,000 kPa for an additional 45 s. PVC-U and PVC-AC were melted at 120° C, pressed at 5,000 kPa for 30 s, and then further pressed at 10,000 kPa for an additional 30 s. Three dog bone samples were cut from these melt-pressed films, and subjected to mechanical testing.
