The scaling predictions for the temperature dependence of the intrinsic viscosity of flexible polymers are briefly reviewed. When the predictions are fit to a power law over a fixed range of chain length, a relation between the exponent and prefactor of the Mark-Houwink-Sakurada equation emerges. In
The zero-shew viscosity r)o of five epoxy resins were analyzed on the basis of the free volume concept. The experimental data, spanning at least six decades in viscosity, were linearized by means of a viscosity-temperaturerelation~ = q,,(T),derivedbyUtracki a few years earlier. The linearization ena
For polymer mixtures with narrow-MMD, the most common types of viscosity-composition and elastic modulus-compositions relations are investigated. It is shown that viscosity anomaly in two-phase polymer mixtures develops, when the polymers have different thermodynamic flexibility of macromolecules. I
