Abstract
Phase behavior of blends of poly(ethylene-co-vinyl alcohol) containing 59 mol% of ethylene units (EVOH59) with nylon 6—12 (PA6—12) containing 60 mol% of nylon 6 units was investigated by cloud point measurements and dynamic mechanical measurements. From the results, lower critical solution temperature (LCST) type phase behavior was found in EVOH59/PA6—12 blends above apparent melting points. To account for this, melting point depression was applied to EVOH59/PA6—12 blends to estimate the interaction parameter, χ, between EVOH59 and PA6—12. The estimated value of χ was −0.58.
