Summary Interfacial tensions (γ) between poly(ethylene-co-vinyl alcohol) (EVOH) and polyamide6-co-12 (PA6-12) were measured by pendant drop method. In the measurements for PA6-12 and EVOH of high ethylene contents, γ's were decreasing with elevating temperature. On the other hand, in the measurements for PA6-12 and EVOH of low ethylene contents, γ's were increasing with elevating temperature. On the basis of these results, interaction parameters, χ, were estimated. Resulting temperature dependence of χ parameters predicted a LCST phase behavior for the blends of PA6-12 and EVOH of low ethylene contents corresponding to our previous study.
