ResumenIn the present communication the fifty/fifty isotactic-polypropylene (PP) and polyamide (PA6) has been chosen as representative of the thermodynamical incompability and then the heterogeneous morphology of an organic polymer blend. It is the most general case when facing a problem of management any fraction of organic plastic wastes coming from big solid waste streams like urban, agricultural or post-consumer out of use organic plastic big parts. The thermodynamical incompatibility between the organic polymers from different structural families, together inefficient processing and/or compounding technologies, it results in deficient set of properties and bad performance. The true possibility to change those morphologies by the presence of different amounts and different kinds of interfacial agents based on atactic polypropylenes grafted with polar groups: Succinic Anhydride (SA) or Succinil-Fluoresceine (SF) moieties is ascertained by the changes in the mechanical and thermal properties of the blends with modified interphase and the morphological changes supported by the optical and emission field scanning electron microscopies (OM and FE SEM).
