NEW POLYAMIDE - BASED BLENDS

Among polyamide based blends, PA/PP alloys show interesting technologi cal 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 morphologi es are related to predictive equations for co-continuity, at given rhe ological 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 blen d composition.
