New polyamide ‐ based blends

Among polyamide based blends, PA/PP alloys show interesting technological properties due to low moisture absorption. A model class of PA6/PP homopolymer blends, compatibilized through the addition of PP‐g‐MA is described in the present work; the experimentally obtained morphologies are related to predictive equations for co‐continuity, at given rheological conditions. PP/compatibilizer ratio = 4/1 is found to impart an optimum level of phase dispersion. Moisture absorption, dimensional stability, mechanical properties and morphology are related with blend composition.
