Abstract
Pectine, a polysaccharide, has many industrial applications, and its miscibility studies are most useful. Synthetic
poly (vinyl alcohol) (PVA) is a subject of current research interest. Hence, miscibility of pectin and PVA in
water is carried out in different percentages of the blend compositions. Ultrasonic velocity, viscosity, density, and
refractive index are measured for these blends in water at 35°C. The interactions in binary blend systems were
analyzed from the viscosity data. The blend compatibility is studied from interaction parameters obtained from
viscosity data. The compatibility of pectin/PVA is also confirmed from the ultrasonic, density, and refractive index
data.
