LDPE/PA6 binary blends and LDPE/PA6/compatibilizer ternary blends were prepared in a Brabender extruder, equipped with a prototype static mixer. Compatibility of the components was estimated by rheological properties (viscosity and a melt flow index), and observations of the structure were made with
## Abstract Three kinds of surface treatment, that is, the alkalization (5% w/v NaOH aqueous solution), the deposition of diglycidyl ether of bisphenol A (DGEBA) from toluene solution (1% w/v DGEBA), and the alkalization combined with the deposition of DGEBA (5% w/v NaOH/1% w/v DGEBA) were applied
The tensile mechanical behavior of an epoxy/amine system, with varying amounts of hardener, was evaluated. The results showed that a brittle to ductile transition occurs as the amount of hardener is increased. This behavior was associated with the change in the number of molecular segments that pres
