Abstract
Miscibility of polyethylene oxide (PEO) with polystyrene (PS) or polyb utadiene-graft-polystyrene (PBS) was investigated by dilute solution v iscometry. Miscibility parameters derived from the classical Huggins e quation were used to estimate the miscibility of these polymer pairs. The results, which indicated immiscibility between PS and PEO, were co mpared with findings in bulk reported in the literature. PBS was also found to be immiscible with PEO. The effect of temperature on miscibil ity was studied by the same method for a blend of PBS with 83% PEO. Al l miscibility parameters were observed to decrease with increasing tem perature.
