Plastic deformation of polyamide 6/polypropylene-g-acrylic acid blends

Two means of plastic deformation were applied to the polyamide 6/polypropylene-g-acrylic acid blends (in two composition 8:2 and 2:8): drawing and plane strain compression in a channel die. X-ray diffraction pole figures, density measurements, SEM, DMTA were applied for studying the structure and properties of oriented blends. It is concluded that interfaces between blends components are weak elements of the blends even in presence of compatibilizing action of PP-g-AA.
