Experimental
The PVC powder (PVC p), PETVINYL E38/74
from PETKIM was ethanol extracted for isolating additives from
polymerization step. Five g PVC powder was extracted with 300 cm3
ethanol by using a Soxhlet extractor. The extracted powder was dried and
called as ethanol extracted powder (EE PVC p). The ethanol phase was
dried to obtain ethanol soluble additives. The extractions were done in
duplicates to produce EE PVC p1 and EE PVC p2. The additives isolated
with ethanol extraction, ethanol extracted PVC and PVC powder itself
were attempted to be analyzed in this study. Films were prepared from
PVC powder (PVC f), ethanol extracted PVC powder 1 (EE PVC f1), and
ethanol extracted PVC powder 2 (EE PVC f2), by solvent casting from
tetrahydrofuran
.
