摘要

The solutions of blends of poly ethylene oxide / PF - 108 ( resol type phenol formaldehyde) were prepared in different proportions in a common solvent. The miscibility of these blends was probed by solution techniques such as viscosity and ultrasonic velocity and a solid state technique such as polarized optical microscopy. Using viscosity data, the interaction parameters of these blends of different compositions were computed with the relevant equations. The immiscible nature of these blends as indicated by viscosity data was confirmed by ultrasonic velocity and polarized optical microscopic methods. The immiscible nature of these blends suggests that these two polymers are favourable for preparing polymer alloys using a suitable compatibiliser.
