Abstract

Studies were conducted on ternary blends consisting of poly(propylene oxide) and poly(methyl methacrylate co n-butyl methacrylate) blended with either poly(hexamethylene adipate) or poly(hexamethylene sebacate). These ternary blends form the basis for preparation of high performance polyurethane-based hot-melt adhesives and coatings. Changes in polyester structure were found to strongly alter the miscibility behavior. Binary interaction parameters for the five polymer pairs were determined experimentally, permitting calculation of the phase behavior of the ternary polymer blends. Results predicted by the model are in excellent agreement with experimental observations. The influence of miscibility in the melt on the morphology development is also discussed.
