Abstract

Blends of polypropylene and nylon-6 extruded into ribbons at varying draw ratios generated laminar morphologies under our conditions. For the binary system, the size and distribution of the dispersed phase is coarse. The addition of an ionomer to the nylon prior to blending compatibilized the phases and produced much finer domains. The tensile properties of the virgin matrix material respond to the draw ratio in a parabolic manner attaining a maximum at intermediate values. Blending with nylon-6 attenuates the effect without improving the tensiles markedly. The compatibilized system however demonstrates greatly improved mechanical properties.
