Blends of poly(butylene-terephthalate) and poly(ethylene-co-butyl-acrylate were prepared in a twin-screw extruder and their morphology, thermal properties and mechanical properties evaluated. No evidence of compatibility was found and the interfacial adhesion between the two polymer phases was shown to be very low. A compatibiliser was produced by mixing a poly(ethylene-co-methacrylic acid) ionomer (Surlyn 8660) with a poly(hydroxyether of bisphenol A) (Phenoxy polymer, Ucar PKHH). Its properties were tested and its efficiency as compatibiliser for the blend was investigated. [Continues.]
