Notes:
It has been reported that the addition of specific copolymers can improve the mechanical properties of blends of polyethylene with polyamide-6. One of these, a poly(ethylene-co-methacrylic acid) (EMA) containing between 4 and 15 mol % of methacrylic acid units, has often been used. Binary polyethylene/EMA and EMA/polyamide-6 blends were studied with the hope that the role of EMA as a compatibilizer in polyethylene/EMA/polyamide-6 ternary blends might be better understood. Differential scanning calorimetry (DSC), laser small-angle light scattering, and mechanical property results are discussed. DSC measurements show that one component of the binary blends does not modify the crystallinity of the other. However, laser small-angle light scattering shows that the morphology of the mixtures changes under similar conditions. Tensile properties of polyethylene/EMA binary blends vary linearly as a function of composition, whereas those of EMA/polyamide-6 blends deviate slightly from linearity. These results indicate no interaction between the crystalline components of the mixtures, and weak interactions in the amorphous phase.
