Kinematic Viscosities of Poly(ethylene glycols)

Kinematic viscosities data have been obtained as a function of temperature for poly(ethylene glycols) with different molecular weights. The viscosity measurements were performed at ambient pressure and several temperatures ranging from 293.15 (or above their melting points) to 363.15 K. A generalized correlation based on the number of carbon atoms was developed, resulting in an average absolute deviation of 1.6% between experimental and calculated results.
